Video games, yes, basically always. I've been bitten too many times on nice but way overpriced, or it has unfortunate DLC mechanics, etc. There are only a few IP that I'll buy without looking up to reviews, like Legend of Zelda.
Books, I tend to read reviews after, mostly to see what other people liked that I didn't or disliked that I missed. Though I'm at the point that "as seen on BookTok" means "probably crap."
Movies and TV shows, I don't bother because I mostly watch Netflix, so no skin off my back if I dislike a particular show. I paid $10 for all the content, not that one episode.
