It's tought to find good stuff these days for sure. Still, not everything is sucky. I usually see what IMDB rating is before watching. If it's above 6 then it's probably good enough.

6+ has always been my threshold, anything lower isn't worth the time invested.
7+ is a great movie and 8-9 is exceptional blockbusters.

Now days however, many movies are 8+ and they are usually cringe and absolute train wrecks.
