The movie went way too fast, it was too eager to show off it's CGI monsters and had so many cuts that it didn't give me time to process what was going on in the scene nor did it go in-depth. It was basically a "hey I know what that's from" movie. I was expecting the movie to end after Diablos. It was also very dark in some scenes, too dark for me to even tell what was going on.
If you're totally new to the whole concept of Monster Hunter, you might like it. As for me who's been around the game since MH3U, it just wasn't enjoyable for me.
