The real challenge is to build a reliable reviews mechanism, then resist the temptation to sell it to media companies.
IMDB moved from a respectable site to a parody of itself for that exact reason: they didn't resist and today their reviews are complete garbage. They got to the point of removing the comments section altogether when users found how to spot fake accounts that were created just to give bogus ratings.

We're IMDB reviews ever good? I used them from fairly early on, but only for actual factual (mostly vast/crew) information, the reviews were always, AFAIR, pretty useless.
