Loved the visuals, especially the underwater scenes as these were awesome in 3D (definitely see it in 3D for this alone) but hated the crappy 'Family' plot. I get that this is supposed to be a family friendly movie but it was a Vomitfest throughout! Zero plot unless you call repeatedly saving your brats plot. It was so bad I'm doubtful I'll even bother with the remaining episodes of this 'franchise'. I just can't face the nauseating Brat Family again for another Vomitfest session... It really was dire! Cameron seems to have thrown the plot to the wolves with this movie. Not recommended except to see the CGI visuals! I expected so much more but this? Just sad! Disappointing and sad! Visually stunning but the plot is SO Crap!
