I liked it

Not as much as the first one but a little more than I expected to. As you'd expect it looks wonderful - better than it did in the trailers. There wasn't anything particularly original about the story but I think they've established a whole new set of characters and I'm guessing the long term plan is to weave story lines for all of them.
If I have any quibbles, it's too long, and perhaps a bit self indulgent. It's a little like a nature documentary at times and I'm sure you could shave 30 minutes off (at least for a cinema release) which would make the last 15 minutes or so more comfortable to enjoy. Failing that, an intermission at the 2 hour point for a quick pee and a coffee would do the trick.
