It was less gags and more plot this time.
Like American horror story, for example
Which I'm not complaining about because it would have been a rehash of the first movie otherwise.
You can still make a sequel with a cohesive plot without being a rehash of the original - Mad Max 2, Lethal Weapon 2, Blade 2, The Dark Knight....
This looked as though they'd filmed the first draft of the script.
