It may just be S1 that I'd watch. I've watched the whole thing before, and man that first season was so good, or at least it was when I watched it for the first time in 2021 off of a friends DVD set.
It heavily features hot girls' tits so, I understand. It was okay for a few season tbh but it definitely got carried away in the last couple. I think the older you get, the more the absolutely terrible acting from some of them will grate on you.
For the record, I started rewatching the first season. If you watched it 15 years ago and liked it like I did, then you will still like it today. I'm way more into this addicting show than I thought I'd be.
I've gone ahead and watched almost the whole thing. Also, I was today years old when I realized that Casey from Yellowstone was a vampire in True Blood. Spoiler Season 6 he's a vampire that refuses to rape Jessica when they are all held captive by the Louisiana Governor)
I think I actually liked the end much better the 2nd time through. Also, I didn't remember the 7th season at all, so I must have just skipped it altogether back in the day.
