Tarm: What enrich my second watch is mostly how the characters and the story interacts. Now that I know the story and how the characters have reacted it makes it much more interesting for me to see those two things grow together. What if thinking is also great at this points. :)
This is also what tends to do it for me too, even beyond the 2nd watch too, and is what I was getting at with Crouching Tiger, which I agree, is a bit more boring than I'd like it to be, but it is visuals make up for it, imo, to be multi-watch-worthy (at least a few times, but I wouldn't have watched it again this time if my partner wasn't sure/couldn't remember it / if she'd seen it before or not.) I also love the blend of martial arts + love story, which is a bit more unique thematically than most films and another reason I like it (not like I think it is superb or anything, I'm certainly not meaning to tout it, though I do recommend perhaps giving it another chance at some point.)
I love martial arts movies, (kung fu a lot), if the martial arts and choreography is well done, regardless of camera-work (though better camera work on the martial arts is very good to have, of course), story, acting, or whatever else. I can sit through some bad shit (like a few of the older Jackie Chan movies) if there is premium kung fu going on to watch.
And yep, there are many reasons to watch movies. I do find a lot of movies re-watchable for thinking potential, some things can get really deep, or are complex or mysterious and need multiple watches to even begin to get a fuller understanding of.
I love dramas, and it doesn't matter the country of origin, if it is done well, I can most likely get emotionally involved and "feel" them pretty deeply, and love doing so. I can like any movie of any genre if it has quality writing and directing. Sometimes the acting doesn't quite come off great, but you can still feel what the writer and/or director are going for, and so it is still very effective at doing its job. Sometimes there just isn't the ability to have better than camera work that simply serves as a conduit for getting across some great writing, directing, and/or acting. And then some camera work is understated and effective, even though it doesn't have cinematic/motion feel to it (something like Tape.)
Altered States is a trip, I highly recommend being on some sort of mind-altering substance if that suits you. It's one of those few that I think should be watched under the influence of something (my preference is always cannabis) - others in that group are Fear and Loathing, The Wall, hmmm, there are a few others, not sure atm, but Altered States solidly belongs in that category (even perhaps more than those 2!)
Zjeraar: I don't understand how you didn't like Children of Men. To each his own I guess.
What made the movie great for me were these tense, edge-of-you-seat moments emphasized by the apocalyptic, depressive setting. It was written and shot in such a realistic way that in every scene I was sure the leads were not going to make it. It was a breath of fresh air after having seen so much of that typical Hollywood-fare where none of the leads are in any real danger (like, I don't know, every superhero movie ever made in any case).
Plus the subject matter was pretty original as well.
I don't always agree with the Oscars, but here the nomination for the Academy Award for best writing (adapted screenplay actually) was deserved.
Ehhh, I didn't get any of that in Children of Men. The acting was bad, the writing was bad, the directing was bad. All of the moments felt contrived and didn't pull off what they were going for for so many reasons. The concept was ultimately ill-conceived as well, it really made no sense. I didn't find the subject matter original at all. And they didn't really convey what was going on, it was just like "oooh, tense tense chaos and run run run!" I remember the writing almost making me puke (that is most of what sticks out, very similarly to No Country for Old Men. Just. SO bad.) Again, I can't think of many details because I don't remember it really. If we were to sit down and watch it together I could take you from moment to moment and explain what I think is bad about it. But that'd be torture for us both, probably.
