How to you get reliable movie reviews?

Last night, we went to see “Sita sings the blue,” an animated film showing - in parallel - two broken relationships: A woman's failed romance with her husband and the goddess Sita's estrangement from the god Rama. While it had all the components needed to make it a terrific, one-of-a-kind production, the story was very weak and was poorly told. It's not that we don't like animated films; Persepolis, for instance, had a (big) leg up on that one. Even though this happens rarely, it's not the first time that we are disappointed by a movie.

This obviously brings me to the core element of the discussion, which is where do we find viewers' reviews, not professional critic opinions, before we go out and invest two hour of our precious time watching a piece and taking a big chance on being elated or bitterly disappointed. Media critics are generally a bunch of snobs whose job it is to say something about what they're viewing. Are they honest and straightforward? I don't think so; they need to feed their column with something, and if there isn't much they can say, they'll make it up. I have done extensive research on the web for an audience review site, but have come out empty handed. Can anyone help me? Suggestions, please!
