Continuity mistake: During the scene where Damaskinos is talking to his lawyer, there is a lot of the jello-like blood substance on his plate. However, when he gets up to go to the pool of blood, there's nothing on the plate.
Continuity mistake: When Blade is fighting the henchmen near the end, he lifts the last surviving one into the air and you can see Blade's hand through the henchman's throat and it is obviously a dummy. Then, when he falls backwards, his hand is not on his throat, it is on the henchman's shoulder.
Visible crew/equipment: When Blade is entering 'the house of pain' where all the vampires are dancing, a crew member is seen at the bottom right hand side of the screen behind a table, pushing a button which makes the door go up for Blade. (00:35:10)
Revealing mistake: When Blade slices Reinhardt in half, as the sunglasses fly off the two halves of his face you can briefly see that Reinhardt (or more precisely the CGI model of him) has no eyes. (01:37:23)
Chosen answer: Killing Scud with it probably was more satisfying for Blade than Reinhardt, who he easily beat as well. He hates familiars and that moment he used the bomb to have Scud reveal his betrayal, and then kill him, so he won't get away. Reinhardt he knew would not try to run, he was killing him anyway.

Agreed. I saw it as he was waiting for Scud to show his hand. Like Blade said, he knew Scud was a traitor/a familiar the moment they turned him. He was waiting for the perfect time to let Scud know that he was already well informed on his betrayal, and that his azz was now cooked. Doing it that way was way more satisfying for Blade.
