I really liked it. Two favorite things were the casting and special effects. Every major character's actor was able to portray their personality and attitude toward things very well, and it gave it a very realistic feel. Not realistic, I mean it's superman, but you know what I mean.
Special effects were off the charts. After seeing the new Star Trek I thought nothing could top it, but this fucking blew it out of the water. I was constantly looking for flaws, but everything was fine-tuned to perfection. The only movie I thought was better in terms of special effects was Life of Pi.
Overall, see it in theaters. I think it would kind of suck on a computer. TV would be alright if you get a DVD
