Yeah there's quite a few I've never heard of too. 4 of the 6 on my list are only on it because DH was watching them and I saw bits and pieces of them. Only Seinfeld and Dexter are not and I haven't seen either series in full.2 - Dexter and The Mandalorian (all seasons thus far)
Honestly? I've never heard of some of these shows. I've not watched one episode of any of them, other than the above-mentioned Dexter and The Mandalorian.
