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. (01:27:44)
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. (01:37:42)
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? (01:18:49)
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.
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 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. (01:18:26)
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. (00:42:01)
