Ok, so I finally had a day off and had time to go and see this movie today.
My thoughts overall is was a good movie, but a horrible remake of clash of the titans, if that makes any sense.
I just think the director wanted to give the fans something new, and people are expecting an updated version of the old movie, with updates to the cgi and such.
So, if you are a big fan of the original, wait for this to come to dvd or w/e so you can turn it off and take it back, and not waste a trip to the movie. Otherwise, go see it and enjoy a pretty good ride.
fyi: i went and saw the 2d version and it looked just fine
