This is exactly what I do, and I think it’s honestly a very healthy way to engage with that kind of content. If you find someone you like, and/or who has a lot of overlap on preferences, then that’s a great way to get an idea for how much you’d like a game.

Hell, even if you don’t tend to prefer the same things, if the person reviewing is sufficiently passionate or entertaining, you can still develop an appreciation for why someone else likes what they do. I’ve absolutely struggled trying to get into Fallout: New Vegas for a variety of reasons, but I still respect it a lot because Hbomberguy had a very compelling video on what he liked about it.
