But I did enjoy and appreciate the X3 joke.
Honestly since this movie only referenced events from DOFP and FC I actually took it as Singer mocking his own film.
I guess I'd say that it was a decent way to spend a couple hours for one viewing. Like others I don't see myself watching this again anytime soon. It wasn't horrible or anything, maybe a 5.5 out of 10 or so. I actually wasn't bothered by Jennifer Lawrence. She always looks so dumb in that blue make-up that I didn't mind that she looked normal for most of the movie.
