There's different levels of enjoyment. Usually "critics" and "viewers". The critics are tasked with determing the quality of the movie's writing, acting, editing, et cetera. Even a horrible movie on the critical side can still be enjoyed. The critics may love the movie, but that doesn't suddenly turn it into a well written, brilliantly acted, and masterfully editted movie.
Recognizing something's flaws doesn't mean that you don't like it. My favorite book series has the worst plot ever. "AND A BIGGER AND BADDER ENEMY HAS APPEARED, WHAT SHALL WE DO?!?!?!?! OH GEE, THE PROTAGONIST IS STRONGER THAN HIM NOW. WHAT A SURPRISE!" I recognize that it is a formula that the author has smashed into the ground, but that doesn't stop me from loving it.
