Well usually the actors are a clue to what the film's like as so many actors are type cast and people know what kind of film they like and what actors are usually in those films. The best way though to find a film you think you'll like is read the synopsis, look at the cover (you can't judge a book by its cover, but you can judge a DVD/Video/Blu-ray by it).[/quote]
Oh, you really are kidding with that one, surely?
If a film was truly awful, or even fair-to-middling, do you think the blurb on the cover is going to tell you that?
Most covers have enticing artwork that is designed to draw you in, and comments from various magazines and publications (the origin and validity of which can often be suspect) telling you it's brilliant.
And worse still, comments from the people that made the film telling you it is brilliant/horrific/hilarious etc.
Well of course THEY would say that, would'nt they?
My god, it reminRAB me of the early days of video rental, when covers (particularly horror movies) were incredibly lurid and salacious, and almost every action movie or thriller had a picture of a man holding a gun on it. I lost count of how many truly awful movies I watched back then, drawn in by such covers.
You really need to do a very small amount of research, read a couple of different reviews maybe, some online ones, a synopsis etc. And it's not that I believe the reviews when they tell me the film is either brilliant or rubbish it's to get a feeling for what the movie is about, knowing what to expect from it, and more importantly what the movie is actually about, as opposed to what the cover is trying to tell me.
Indeed, cover art does a similar job to trailers. The idea is to persuade you to buy it based on some pictures and lots of complimentary comments on how good it is, and why you simply have to see it.
Surely no one actually buys a film simply because of the cover?
