Which movie rating platform do you trust the most?

I used to work with the mouth-breathingest of morons who had infallible taste in movies. If she hated it I put it on my watchlist.

I use letterboxd for everything but reviews (I never read them unless they are from friends), and I love it. The user experience is just great. The webapp is lightweight, looks cool but isn't cluttered or unnecessarily fancy. I'm provided the relevant information I care about right where I would expect it to be. I sound like a shill, but I enjoy their website a lot :D
