Using Overrated
I understand that some people did not enjoy this film, which is fine. I care about your reasons why you don't like it and I know that opinion is something of value to you. One key note, however, is that you give the same respect for the people who enjoyed the film as well. If you find the film overrated to you, then keep it to yourself. Calling it overrated is disrespecting many others' opinions of the film. Like how I will not call you various names, do not call the people who enjoyed the movie as "superficial" or "gore lovers".
TLDR; There's always different values people enjoy and try not to demean that to anyone.
