Other mistake: The werewolf gets blown to pieces by the dynamite, clothes and all. I can understand how the werewolf can reassemble his body as only silver can kill him. But how in the world do his clothes knit themselves back together?

Suggested correction: It was a nod to the comment Sean made earlier in the movie about Wolfman wearing pants in the 40's so you wouldn't see his "wolf dork"; it was meant to be a joke.
Other mistake: There is a lot happening at town square in the final scene; the kids are trying to get into the church, Rudy is killing vampires, and the German guy parked in front of the church. But in the overhead shot where we see the bat flying, there are no people or cars visible near the church at all.
