I've had a few times where I'll look at a random movie on some streaming service that I haven't heard of before, trailer looks great, genre is right up my alley, I'll watch it, it's not great but I hope it gets better and then by the end I realise it's bad.

So I go see the RT score and it's low to mid rated for both critics and viewers. So after a few of those I started our checking. For ones I haven't heard of. Found it very useful so far
