Yes, I look mainly at Goodreads reviews (or Audible if it's an audio book). I feel like anything with a avg rating above 4 is worth reading (if you are into the genre of course).

I would actually appreciate it if it were possible to give half stars, many five star reviews of mine would probably be more like 4.5.

5 - loved it, could not stop reading/listening to it, would recommend it without doubts

4 - liked it, enjoyed it a lot, but not quite as thrilling / absorbing

3 - just ok

2 - part of it was enjoyable, but generally did not like it, probably took me longer to finish when I am reading multiple books at once

1 - absolutely hated it, considered stopping reading (I try not to DNF)

My average rating is 4.08, but I tend to do a lot of research before picking up a book, that keeps disappointments to a minimum.
