The entire "movie" consists of designed-for-3D CGI displays meant to make you want to see the actual movie because it's pretty and some hastily sketched, teaser-y plot scenes to make you interested in what the movie might be about.

Too bad they forgot to make the actual movie out of it!

There's no director leadership; there is no screenplay; there is no script, no actual writing and development of characters. Same actors play seemingly same characters that behave completely unlike the in the first movie. We are told offhandedly, "oh, did you know, what you saw happen in the first movie? that didn't happen, move on, oh, that other thing didn't happen either, move on, oooh, look, 3D kitties!"

It's like someone hastily scrawled an bulleted list outline for a possible movie on her knee 10 minutes before deadline, and another someone just filmed scenes that roughly correspond to each bullet point.
