Second one definitely has the aura that the animators didn't really want to make it, but were forced to because the first movie made a lot of money. It's probably the first time I didn't laugh at anything Andy Samberg said or did, which is saying a lot since Samberg's one of my favorite comedians ever.
Although admittedly, I am kinda excited for the third one. For whatever reason, it looks like with this movie, the animators are having a lot more fun and being more creative, and the cruise angle seems interesting.
