Only heard poor things so far although I still want to see it. Had this included 3D is definitely have snapped it up, particularly as that was a focus with this film, but no inclination until a price drop now
Just got back from watching it. Very mediocre film, probably rate it 5/10. Some decent action at times but the majority of it is boring. I watched it in high frame rate 3D, which just reminded me straight away of the Hobbit movies. Soap opera effect kind of kills it a bit.
Also, the things they can do with CGI these days. Young Will Smith looks amazing for 95% of the movie, just looks a bit crap in the scene at the end of the movie. Would be interesting to see if a different company did the CGI for that or if it was an earlier produced scene, idk. The bike scene was probably the best bit
