I loved King Kong, apart from three scenes that were way too long. One, the dino chase sequence. Realistically, everyone involved ought to have been crushed to a pulp inside of ten, twenty seconds tops. Yet it goes on for what, two, three minutes? I'm not sure. Way, way too long anyhow.
Second, the capture of Kong. Overly long and way overly melodramatic.
Third, death of Kong. Yeah, we know it's meant to be a sad scene, but it becomes too much when it goes on and on and on, on top of the capture sequence.
Juicious use of the editor's scissors, snip-snip, and the movie would have been better off for it. As for the rest, I love the mystique, the misty sense of wonder given by the period nature of the film itself, underscored by James Newton Howard's awesome music. The actors are all good, even Jack Black strangely enough, and also Kong himself. The Kong vs. 3x gigantic T-Rexes stand out - in my mind at least - as one of the greatest and most imaginative action sequences of all time, and I also love the Central Park dream-like sequence. Very sentimental, in a positive sense. In my mind anyway.
Oh, and I also watched Prometheus today. It was alright, worth the money but doesn't stand out as an all-time greatest movie in my mind. It wasn't as much a horror movie as mostly just gore and grossness, there were a few creepy scenes, but you could count them on the fingers of one hand, and they weren't particularly scary, or even tense for the most part. Nothing like the original Alien, or Cameron's Aliens, which both scared the heck out of me when I saw them in my early/mid-teens...
It was technically very well done of course, as might be expected. Hardly any dodgy effects work, the sets look great; not as grimy as the original movies (but you wouldn't expect that either in this particular case), but still very recognizable as belonging to the Alien universe.
Possible spoilers ahead, so avert your eyes if you care:
What I didn't really like was having a very creepy android named David (who turns out to be quite psychotic) with roughly the same timbre of voice as H.A.L of "2001" fame, whose other main character was named Dave. That is a rather too strong a connection in my view, and hints in a much too un-subtle way of what is yet to come. I don't think anyone watching that movie doesn't suspect David right from the start, unlike the case with Ash in the original Alien, whose only suspect moves early on in the movie is the strange jog he does before settling in at his post, watching Dallas and crew head off to the alien ship, and his eerie calmness about the whole situation once people start dying.
Also, the Space Jockey didn't die in the pilot's seat like he was supposed to, so he could be found by said Dallas and crew. I assume this is a direct precursor to the movie Alien, where they find the Jockey in his armor, at his seat. Else this was not the same ship as found in that movie, but that seems weird too. I find this a discrepancy in the continuity.
Also, David seems to have knowledge of what the contents of the bottles he recovered from the store room would do to human beings. Where did he gather that information from, or did he just guess? I don't think so, based on his dialogue. This is another discrepancy, in plot this time, perhaps explained by cut scenes that will appear on the blu-ray director's cut release or something...
