I'd say it's a worthy addition to the Star Wars series and fits in very well.
-Lot of connections and similarities to the first film. But it worked.
-Like seeing "The Hobbit", you've just paid $15-20 to see a movie about spaceships, robots and wizards... so don't try to be cool. Just enjoy it.
-Since Star Wars (proper) left movies in 1983, we've seen more modern sci-fi flicks and thought: "hey, something like that would've been cool in Star Wars". Thinking of flicks like "Aliens" and the relaunched "Battlestar Galactica" series. Felt like those were worked in.
-Glad they found Luke in the final minute. I was dreading that they were going to end with them flying off to find him and thinking it was all a set-up for Episode 8. So, yay.
-My first thought when they found Luke:"oh shit. It's the island from LOST. This is going to suck".
-Y'know, it may very well have been the same filming location for parts of LOST. Those rocky crags and shores looked familiar. Same way Peter Jackson re-used sets he liked for "Lord of the Rings".
-My second thought when they found Luke: "hey, he looks good OLD! Actually... he kinda' looks like Oliver Reed, now".
-No way to tell while watching, but Daniel Craig as the Stormtrooper was a fun Easter egg.
-I figured the big DEATH was coming... because the new Big Bad Guy needed some way to get the audience to dislike him. Aside from dressing in black and being all mean. Now, we think he's a giant asshole emo douche-bag.
-Also glad they didn't tease Kylo Ren's unmasking and his connection. It was established about 1/2 way through that he's Han and Leia's kid. With enough new questions, this is one we didn't need hanging.
-I expected more background on Finn's switch. He sees blood and decides that being a Stormtrooper sucks. This will probably be filled in more, as we go on. As it is, his motivation doesn't seem justified.
-While the speculation is that Rey is Luke's kid (or Obi-Wan's grandaughter), I'd put my money on her being Kylo Ren's twin sister. They seemed to be symbolizing that in her duel with Kylo Ren. Plus the way she gravitated to Han..and it makes her big hug with Leia seem all the more important. It's said that twins run in the family.
-Yeah, so the Millennium Falcon AND the Old Guy with Vital Info are both on the same planet as Rey? Seems suspicious.
-"Supreme Leader Snoke"? Errr. Probably the weakest part, to me. He reminded me of "Imperious Leader" from the 1970's "Battlestar Galactica". That's not a compliment.
-They made the First Order come off like straight-up Nazi cockbags. Especially in that giant troop scene. Nazis were supposedly some of Lucas' inspiration for the original Empire, so that was appropriate.
-In the final battle(s), I kept thinking: "please let Chewbacca survive! Please let Chewbacca survive!" I would've cried like a baby if they had killed off Chewie. I was extremely happy when he showed up in the Falcon. As I've gotten older, I just frickin' love Chewbacca all the more.
-Along those lines, I think the only good thing the prequels gave us was those 45 seconds of Wookie Army Ass-Kicking.
