Great movie. It definitely wasn't without faults, though there are precious few of movies that exist, but still a good movie.
MAJOR SPOILERS INSIDE! YOU HAVE BEEN WARNED!
Spoiler!
Okay, I had predicted Solo was going to be the one that would die, and that turned out to be true. I'm alright with that, especially if it's going to be in a heroic way. And, I guess it kinda was. Trying to win his son back from the Dark Side is admirable and all that. However, it just didn't quite seem to have quite that "moment" I would have expected. Based on the trailers, I had kinda expected Han would have been the one to intercept Kylo from killing Rey and that's where I thought he would fall. Personally I think that would have been a bit better of a death for Han Solo and would likely have fit his character a bit better. I also have to echo the sentiments about Chewie. I would have expected him to blow the detonators and then go bezerk on anyone nearby. Again, seems like that would have been more inline with his character.
Also, Captain Phasma... not quite sure what to make of her. I'm sure she'll play some bigger part in the later movies, but it just seemed odd to have a character like her in the movie when all her lines could have been said by a random stormtrooper.
Lastly, I think Starkiller base should have simply been disabled at the end of the movie and not destroyed. In a movie that echoed Episode IV very strongly, having yet another massive Empire weapon destroyed was a little ho-hum.
All that aside, and they're more or less nitpicks than anything else, it was still a great movie. I did like how they didn't introduce Luke until the very end of the movie. There were already so many main characters that having even just one more would have made it feel too crowded on screen. I think JJ captured the essence of the original trilogy, even if it was a little derivative, and brought it up to modern times.
There were definitely some nostalgic moments to be had, and a manly tear or two may or may not have been shed.
