I just got back from seeing it as well, and I agree. The critics are being pretty harsh.
The only thing I really wish it would have had was more action. The trailers pushed the action sequences and yet the movie felt less action like. I do know a lot of scenes got cut as well. I also think that Jubilee must be cursed, considering she has cameos in 3 X-Men movies, was originally going to be in Days of Future Past, and was finally put in this movie and then almost all her scenes got cut that just isn't good luck.
But I do believe this movie finally got so many characters and plot points right.
