I had it for a few months last year, I mostly watched the DC shows on there like Superman and Harley Quinn. Also Josie and the Pussycats lol. I watched Oz too and I really liked it, very addictive show.
I always use Justwatch to easily see what shows and movies are on a streaming service: https://www.justwatch.com/us?providers=cru,hbm
Just looking on there Babylon 5 is a really good classic sci-fi show since you have some sci-fi on your list. I have heard Westworld, The Outsider and Person of Interest are good. True Blood is quite popular with people but I'm not into pretty vampires.
