Finally saw this today in 3D. I liked it a lot, much better than the first one (I have seen the first one only in HV, so can't really compare). Very colourful and pretty, imo the visuals looked better than in the Jungle Book. The score was also good. Don't really understand why people mock the plot so much, I think it was good althou pretty straightforward with no real twists. But I think in a movie like this there is no need for twists and turns. Also liked the idea how one small incident can have large consequences and that one cannot change the past; basic rules of life.
Overall really entertaining with happy ending what more can one want as life itself is too complicated. Hell, I liked this so much that I was even happy to see the "Eragon-guy" in one of the smaller roles
Edit: SBC and HBC were brilliant, Johnny not so (I did not like the Mad Hatter in the first either). Alice was solid.
