I'm confused about some plot points...
First off, did Ben stay with his dad his whole life, knowing his dad was a werewolf? Or did he not know? It seems strange that Ben wouldn't notice his dad suddenly gone three days a month for decades without asking why.
Second, it seemed like Gwen's romance with LT was really quick. I felt she barely got her fiance, who happened to be LT's brother, into the ground and she suddenly feels an attraction to LT? It just seems very weird to me, after only a couple of months, she'd be over grieving (which was a pretty big deal in the upper classed in Victorian times) and kissing LT. I just don't think a woman of the Victorian era would do that. I don't know, kissing the brother of your dead finance is sorta gross. It just didn't seem real to me.
Third, if the dad was a werewolf, how did he keep it a secret? It seems this Wolf Man, unlike the older black and white version, runs amok and has a huge body count. I know, the dad locked himself away, but why was he suddenly out? If he was because of Ben, why not just bite Ben and turn him into a Wolf Man so he wouldn't be with Gwen instead of kill him? I am sure since he has a servant, that man could have the werewolf bite Ben without killing him. It just seems like a big plot hole...that LT was in American but Ben wasn't...unless I missed something.
