I'm pretty much in the same boat. While I was watching it, it was fine. Funny stuff, action stuff, drama stuff, Star Wars stuff.
I try to avoid spoilers and pretty much anything else about a movie until after I've watched it, then afterwards, I like reading what others have to say. I often get more out of the original experience, because people point of stuff I'd missed and other cool stuff I didn't even realize. In a sense, I get more out of the movie because I can appreciate more of what it did.
In this case, however, there was a lot more "So that's it? We never find out anything about Snoke? Rey's parents were nobodies? Luke and Leia's final scene together didn't actually happen?" and so on.
So I did it to myself, because I was okay with the movie until I realized all the stuff it didn't have and didn't explain or follow-up on from The Force Awakens. After I watched The Force Awakens, I was expecting all that stuff, but I guess I'd forgotten all that. A lot of movies are like that; plenty of fun to watch, but if you think too much about it later, you'll realize that there are holes.
