What your philosophy - watch something whatever, or prescreen out the duds/non-suitable first? If the latter what sites?
For DVD's I mainly turn to Rotten Tomatoes, but sometimes this is after I've bought the 'bargain' DVD on impulse. e.g. I've still not watched 'The Happening' I once bought from Tesco as it achieved a massive 18% on RT.
And for suitability for the family, yes, Christian Spotlight on Entertainment... CSoE is a tad 'over wrought' with relating film content to the bible, but they do usefully give a detailed idea at the end, of the level of swearing/sexual content. From a family POV, because some 12 rated films are pretty lax (AFAIC) on this front quite handy IMO.
