One guys "crap" is another guys entertainment.
The problem is that any given reviewer wont "mesh" with what *YOU* like. Or what *I* like. In the dark ages (before www), I used to religiously read two or three movie reviewers in my area. After 5 or 6 reviews the lights clicked. If X liked a given movie it would be likely that I WOULDN'T like it. If Y liked a movie, then it was pretty good odds that I would enjoy it. It was a bit more complicated than that but that's the gist. I learned what THEIR criteria was pretty quick.
Occasionally, I'd see a crappy movie my "rules" would indicate I would enjoy it or vise versa but it was otherwise pretty accurate.
Good example of an exception -- Back to the Beach (1980s reunion movie). I did *NOT* want to see that film. Some friends and I went to see the latest Bond film (can't recall what it was) but it was sold out. They decided to see this and I didn't drive. Everything told me that this movie would be crap. I'm embarrassed to say I enjoyed it. The opening on the airliner set the tone and it was just fun to watch. My "rules" told me to avoid this film like the plague.
