Saw the trailer in 3D today on the big screen (went and saw the Superman movie - it was only okay, if anyone's on the fence about seeing it), and honestly, I didn't think the CGI looked all that bad, though I'm hardly an audio/videophile so it would probably have to be pretty bad for me to complain about that. I have a much bigger problem with the
content of the trailer and am really leaning against seeing the movie in theaters (definitely wouldn't, except my husband really wants to see it - although I've already annoyed him half to death with complaining about AUJ so maybe I shouldn't see it with him

).
Actually though, now that I think of it, other than the Legolas/Tauriel bit and the uncovered barrels there's not that much in the trailers I specifically object to... it's more just that it just looks like more of the same swollen drivel that filled the first movie.
