I finally watched it today. Overall, it certainly was enjoyable, but I have yet to make up my mind about whether I really liked it or not. I think a part of the problem is that it really does feel more like a reboot than a sequel. But at the same time, it is exceedingly well put together. Some quick thoughts, most of which have already been covered...
1. Yes, the Death Star is definitely the curse of the film. In some ways, it's almost inevitable, because the villains in Hollywood films have to keep pulling out bigger and bigger guns. So, what's bigger than a Death Star capable of blowing up a planet? Well, a bigger Death Star capable of blowing up multiple planets at a long range. Umm, ok, but where will you go from there, Star Wars? You can't keep on repeating this forever. At the same time, in defence of the new Death Star: it really didn't bother me while watching the film. It only started bothering me afterwards. As long as you're in that space, immersed in the story, the new Death Star seems to be just plausible enough in this context that you don't really worry about it.
2. The Hitler speech. That really was weird. It's something that's virtually unimaginable in the earlier Star Wars films, and certainly seems to make no sense here, either - why would storm troopers, who are brainwashed and "retrained" at the slightest indication of problems, need this kind of motivation? More importantly, why does the audience need it? I guess it's mainly there so that the film doesn't have to explain to us what the planets being blown up are - that is, why are they important.
3. What is up with the New Republic and the Resistance being separate organisations?
4. The "desert planet" thing actually didn't bother me, except for one detail: even though they mentioned its name over and over again, it took me the longest time to finally accept that this is not Tattooine. In that regard, they probably would have done better had they picked a vividly different landscape - if you want a desert-like landscape that retains a strong sense of being different to an actual desert, go to the Mongolian steppes, the Canadian tundra (in the summer!), or whatever. Or, you know, just don't make it a new planet, and instead set the action on the real centre of the Star Wars universe, Tattooine.
5. I definitely like how little exposition there was - hugely different to the prequel trilogy, which constantly overdosed on exposition. That having been said, there were still moments that seemed excessive, in particular when Han Solo does his speech about the Force being real. Yeah, we know, we've watched the films.
6. The last ten minutes of the film were utterly gratuitous, and seemed to really only be there to allow the film to be marketed as bringing back all the main characters of the original trilogy. In the original trilogy, the film would end at the victory celebration. What's-her-name's voyage to the end of the universe and facing a (speechless) Luke Skywalker would either have been the opening of the next film, or perhaps skipped entirely, and only described in the opening crawl.
7. Given how the film is being accused of fan-service so much (and in some aspects, quite justifiably), it's really quite funny how we never, ever see a single new space ship. You'd think someone, somewhere, would design a new fighter, some sort of new X-Wing replacement. Or a new Tie Fighter. But no, rather than giving the fans what they want, the film seems to want to give the public what they want, which is basically more of the same instantly-recognisable stuff.
8. Am I the only one who found that at the end of the day, I couldn't care less about Finn, and certainly felt no great drama upon seeing him comatose? Also: isn't it a remarkable coincidence that the only Imperial turncoat we've ever seen happens to be black, while all the other Imperial officers we see seem to be white? It just feels odd.
