I thought it was mediocre. It was trying too hard to be a more artistic intelligent movie than the first one - at the same time going for slapstick in really bizarre places. It was incredibly beautiful looking but come on...
(highlight for spoiler)
If Calypso is so pissed off, and so powerful, howcome she only creates a puny maelstrom that lasts for about 10 minutes? That's all she does. It's not even strong enough to suck anybody in. Then she just goes away? I mean wtf.
Anyway, the scene with Jack and the pebble crabs...hilarious. This film however had no emotion. For me it was soulless. This was by no means a terrible movie, nor was it embarrassing to watch. It just lacked heart and sincerity and overall felt bloated and dull.
