I generally don't like social media, but Letterboxd is an excellent alternative to review aggregators, as you can find individuals with similar tastes to yourself. I've found many films I've greatly enjoyed via my Letterboxd network that I would not have otherwise.

For now. The same thing that happened to GoodReads will also happen to Letterboxd. Nobody wants to pay for a service like that to stay true to form in the long term.
I only casually use it to find books I might like. So far I've not noticed anything changed since Amazon acquired it (didn't even realise they did, in fact)
