Interesting. I wonder if this is the right way though. Firstly because the RT critic score was gamified a while ago, and secondly because there's often a big gap between what the critics think and what the audience thinks. (One of the things I like to do is find movies on RT where the difference between the two is the biggest) Even if you ignore the fact that some reviews will be sponsored and not made entirely in good faith this is assuming that critics' judgment is a good signal in the first place.

I think all of this is addressed by matching you to critics who like and dislike the same shows as you like.
