Corrected entry: In the sewer scene Reinhardt melodramatically puts his hand under one of the holes where sunlight is passing through and we see it starting to smoke. He is wearing gloves, why would his body react to the sunlight while it's covered?
Corrected entry: During the sewer scene, Whistler says "well some of us can't see in the dark, nipplehead". Fair enough, humans can't see in the dark, vampires can. So why do they have the lights on the guns? As a UV weapon, constantly on but filtered for quick access? That's just about OK. But that doesn't explain why Nyssa uses a flashlight in the house of pain as she searches the rooms/corridor/loft.
Corrected entry: When Blade is fighting the masked Nyssa at his base of operations near the beginning of the film, towards the end of the fight, there are two shots that are created entirely with laughably bad CGI. The "characters" move WAY too fast, have unnatural "bendy" movements, and defy the laws of physics a few times, making them completely unbelievable. (The exceedingly low-quality of these shots is even joked about in the audio commentary).
Corrected entry: Nyssa describes vampirism as an arbovirus where vampires are the vector. However the definition of an arbovirus is as an arthropod-bourne virus - arthropods are invertebrates with exoskeletons(insects). Not vampires.
Corrected entry: When a person is turned into a reaper, their lower jaw is supposed to drop out (as is obvious when they open their mouth 'proper' and feed on someone. Look at Nomak in his final fight scene with Blade. His lower set of teeth is quite visible, but they all disappear when his mouth opens.
Corrected entry: The heavily armed heroes walk around a nightclub. One even wields a drum-fed heavy machine gun - and no one in the club seem to notice or remotely care until people start shooting. Surely armed assault teams aren't that common a sight in these places?
Corrected entry: Towards the end Blade is strapped to a table and has spikes run through his wrists and thighs. Later he regenerates himself in blood and the wounds are healed. Fine, but there are numerous times after (the fight with Nomak, etc.) when you can see there are no holes in his pants from the spikes in his thighs.
Corrected entry: In the House of Pain, when Nomak and Blade are fighting, Nomak runs away because a ray of sunlight hits him, but before that, when he gets shot in the head, he runs down some stairs full of sunlight. The sunlight on the stairs stopped Nyssa from running down them but how come it didn't effect Nomak seeing as that hall of stairs was full of sunlight when underground, there was only a little ray of sunlight.
Corrected entry: After Blade emerges from the blood fountain, he fights a lot of henchmen in hand-to-hand combat before taking on Reinhardt with his sword. When Whistler shoots the incubator after Blade kills Reinhardt, where are the bodies of the ones Blade fought hand-to-hand? None of them were vampires, so they wouldn't have disappeared.
Corrected entry: In the scene where Blade meets the bloodpack for the first time, and is telling Nyssa they should go to safehouses, you see in the background that Priest(the long haired one) is wearing dark shades. The camera cuts off him, but when it goes back to him, you can see that he is now suddenly wearing clear glasses.
Corrected entry: In the first blade movie if blade did not take his serum he went into shock and became incredibly weak, yet in the sequel he intentionally sets his serum aside after speaking with Nyssa and can fight just as well without any noticeable change.
Corrected entry: When the UV bombs go off in the sewers, the reapers are burned but you see their dead remains as scorched statues. Yet, when sunlight hits reapers, they completely disintegrate into ashes. What's with that? It's all UV light right?
Corrected entry: In the scene where they first encounter the reapers in the rave (right after when Reinhardt is shooting the reaper with the shotgun) Snowman is confronted by a reaper wearing sunglasses. The camera goes back to Snowman then back to the reaper who now does not have the sunglasses.
Corrected entry: The vampires know that the reapers can't be killed by guns so it is unlikely that they should go into the sewers armed with guns and spend their time checking the guns before the fight.
Corrected entry: During the fight scene in the tunnel, the cartload of UV bomb explodes, instantly killing everyone, save Blade, and the 2 vampires. But this shouldn't be possible as light cannot bend, and therefore, the UV bomb would only be effective on the reapers around Blade - it can't go around corners.
Corrected entry: In one scene Whistler has a thermal scope on a rifle and looks at Blade walking with a group of vampires. Blade is red (warm) and the other vampires are blue (cool). Later Whistler is walking in the tunnels with two vampires from the earlier group that were blue in the scope. They give him a night vision headset so he can "see in the dark". When he looks at the vampires with the night vision they are both red (warm).
Corrected entry: After Blade and Whistler are taken prisoner by the vampires toward the end of the movie, Blade wakes up, feels around on his person for weapons, and Whistler tells him that they took all their weapons. Then, when Scud is holding the bomb that Blade had attached to the back of Reinhardt's head, Blade pulls out a detonator, and blows Scud up. So where did Blade hide this thing? How did the vampires miss it when they removed all his weapons?
Corrected entry: When Nomak is admitted to the inner part of the blood bank in the first scene of the movie, the female tells him they found that his blood has a very rare phenotype. They strap him down, intending to take all his blood, and are apparently shocked when he turns out to be a vampire. But when Dr. Jenson examined Quinn's blood in the beginning of the first movie, she saw that his blood was highly unusual, in that it had biconvex red blood cells. While Reaper blood cells may not be identical to those of conventional vamps, if these guys examined Nomak's blood, they should've at least seen immediately that he wasn't human.
Corrected entry: In the beginning, after Whistler is rescued, he says something to the effect of "they could've at least fixed my leg." If Whistler were a vampire for more at least two years as the plot indicates and been left to heal in a vat of blood, his leg would've already healed, due to the regenerative capabilities of vampires.
Corrected entry: Towards the end of the film, Whistler escapes from Reinhart and finds Blade on the lab table where his blood is being drained. Blade's shirt/combat vest has been removed. It was mentioned earlier by Whistler that the vamps had taken all of their weapons, but later when Whistler is escorting Blade into the blood vat chamber, under fire from Reinhart, Blade is wearing the combat vest.
