Like everyone that's seen it, this movie is much better than the haters would have you believe. My expectations were very low, just based on the trailer, however it seems all the worst moments were actually shown in the trailer.
Movie stands on it's own merits, not better than the original but a very decent modernization of a classic. Solid acting, well written, some of the best "3D" effects I've seen on screen, Hemsworth was a lot funnier than expected.
Ultimately it's a movie I'll say go and watch yourself rather than listen to the haters that have ranked it super low before they have even seen it.
