Wow. Let me just say if I could save this post into a folder of "favorites," I would.
The third movie felt REALLY disconnected/bigger picture to me than the first two films - and this is one of the reasons I think I have such an unemotional tone to it - I didn't feel involved
in the scenes quite like I did in the first two. It's not that I didn't like it (as I think over scenes, I LOVED them individually) - but it's like I wasn't as close to it, and so don't care as much, if that makes sense.
So in that sense, I felt Battle: LA was a better movie in terms of an alien-invasion flick.
Now that I've gotten that out of the way, to try and keep on topic, I must say I've seen very few films with extensive knowledge/background in their roots. Yes, I knew about Spiderman, X Men, etc. before their films. I could name some of the main villains and in the case of X Men, the protagonists, and some of their story. But I never got deep enough into any of them to be able to say definitively "oh, that should have been so-and-so not him doing that," or "That's referencing the wrong thing!" or, "They can't do thaaat!" :[
So my attempt to stay on topic is pretty weak. D:
