Okay, just to confirm.
I've now seen this movie in regular and 3d.
There is one word to describe it. Epic.
One can argue that the plot can get somewhat cliche... but the wonderful thing is I couldn't have cared less. The way the movie flowed, the way it was created and the way the characters were fleshed out and portrayed.... was pure genius. The cinematics throughout the movie are nothing less than jaw-dropping. I found myself literally attempting to reach for a nonexistent remote a few times in the film just to pause the movie and stare.
It has been awhile since I have watched a movie and been inspired so much that I wanted to jump into the fight myself (The Last Samurai was probably the last one, but only because I have a strong connection to that but whatever that's beside the point). It has been a long time since I watched a movie that actually had me caring what happened, and even though I knew what was going to happen once or twice... I was still glued to the screen as if to make sure that shit happened and if it didn't I'd jump into that screen and fight or something. I was pumped, and that feeling is what should define the movie experience. 2 hours and 40 minutes? It felt more like an hour. It sucks you in and never lets go man.
For me, at the very least, this movie was nothing short of pure epicness and I say that with full confidence. Hats off James Cameron, you're the fucking man.
