the last act is a complete mess. they added too much.

I Do like the movie for most of it, I liked the jokes and i liked dracula trying to make the boy become a vampire. That all was really nice and for the most part it flows.

But once the Boy's birthday party happens, the movie falls off the rails. it becomes a mess... Once the grandpa and Bela are introduced the movie just becomes very messy. The ending Almost ruins the entire thing for me.

Bela is annoying, he is not funny, the introduction of the grandpa vampire to meeting the other characters is too abrupt.They should have build it up more from the beginning,
Then when he finds out there are humans in the party and when Bela attacks to boy and the wolf girl, it just becomes a mess. the tone changes too much from dramatic to action to humor all over the place.
Everything is too loud and things are happening too quick

and then when everyone starts to beat up the bat demon creatures it became ridiculous and pointless. why would a little 5 year old be able to beat up all of the monsters like that? I KNOW it is just a kid's movie but it just for me ruins the ending.
that action sequence is just very unnecessary and doesnt' add anything to the story.
