I find it's often the other way around, people shape their opinions of movies based on what critics think. Many people don't have the capability to give their own assessment on things.
But as far as Super Hero movies go, they all have virtually the same story, so it makes them predictable:
1. Villain introduced.
2. Hero successfully defeats some villains to show off abilities.
3. Villain starts working towards their goal.
4. Hero starts working towards theirs.
5. Hero seems to be largely successful in his/her/their efforts.
6. Villain does something devastating, and it now looks like everyone is doomed.
7. Hero finds some sort of way to defeat the villain, and it works!
If the movie is part of a series arc, #6 and 7 might be flipped around, where it looks like the hero is about to defeat the villain, and then the villain pulls out the stops and comes off with the victory. Usually the consequences aren't as bad for the side of good, because the evil plot is still shut down to a certain extent.
Every super hero movie I have ever seen fits this formula.
On the topic of Apocalypse
It was disappointing to see him so completely destroyed after just one film; without doing some of the really interesting storylines he was in, I was hoping he'd be more recurring like Magneto and Stryker. On the other hand, seeing him destroyed by the Phoenix was a great treat; it was a battle I've wanted to see since I was a kid.
Also, it looks like Sinister is going to be in the next Xmen movie.
