Everything I wanted it to be. If you were a big fan of the originals and were waiting for them to FINALLY release a new film with the original cast then the wait is over, and boy was it worth it.
This film was so funny with lots of laugh out loud moments, a reunion was the perfect way to bring all the characters back together, and when I say all the characters, I mean ALL the characters. This wasn't done half-heartedly they literally got everyone from the first film in it.
Basically, if you liked the original 3, you'll love it.
