Well, one shouldn't go by any reviews because there's no saying whether your opinion of a movie will match that of the masses &/or critics.
I only read/watch reviews after I've seen a particular movie. It's mostly to see why others have liked a movie which I haven't. & more often than not, they seem to be singing praises about aspects that I felt actually failed or were average.
I usually give a rating here in the hope that there might be someone else who feels similarly about a movie. That would just help with the feeling that I'm not the only one who felt the same & consequently that I'm not just a cynic or simply hating for the sake of it.
I've often questioned myself over whether I'm hating on it simply because it's fashionable to go against the popular opinion. The answer, of course, is that I simply have different tastes or expectations.
My other hope with providing a rating is that it'll spark some discussion about the merits or de-merits of the rating. But people here are too civilized to try & foist their opinion on something as subjective as movies,
.
There have been many widely acclaimed movies which I personally felt were nothing but over-hyped - Avatar & Gravity, to name a couple. They were all mega-blockbusters.
The success of a movie at the box office is not a barometer of how good the movie is. Especially now, when just about any big budget movie rakes in the moolah due to the hype generated & because folks don't have anything better to watch.
TL;DR - Reviews don't matter. You may very well be an outlier.
