I enjoyed this too, although some of the critics didn't. It had everything in it that I enjoyed from the first movie.
Some of the gags were very predictable but nonetheless still funny. There's a tank with a shark in it, what could possibly happen next ?
The scene after the credits is again fairly predictable, it's the "we might want to make a third film" scene.
I can't go into more without some serious spoiling, but I reckon if you don't overthink and just enjoy what's in front of you, if you enjoyed the first film, you'll enjoy this one.
Example of critics overthinking: A really cliched cheesy boyband appear briefly, they were apparently IRL on a reality talent show. This really grated as a form of product placement with the critics, I saw a boyband that were in the film to have a particular effect on teenage girls, could have been any boyband, and I found that scene hilarious.
