Site to compare movies ?

Hi, just a quick question. I used to have the link to some site where you could enter the name of a movie and you’d get suggestions for similar and/or related movies .
Anyone know the name ?
Answer #1
Does imdb have that option?
Check imdb site, maybe it helps.
Answer #2
I know but that wasn’t it. Thanks anyway.
Answer #3
Oh, ok, was worth a try.
Answer #4
There are a lot similar sites like that… I know exactly which one you want but the name escapes me and I’ve lost some of my bookmarks… it was one of those
Anyway, the 2nd best probably is
