The first movie did the annoying thing of the first time back after the supposed "ending" unwrapping everything the ending put in place. The second film seems to have done that with the first movie with the fact that any of the girls from movie 1 seems to have either dumped them, on a break or gone crazy therefore just reverting back to square one. I get it but I'd like to actually see these characters progress through the reprecussions of the last film rather than just essentially pretend it never happened.

I think that's because they want to keep the characters as losers because theyre funnier that way
The punching koala bears bit made me laugh out loud.

Having said that the second film is meant to be a step up.
