I always found that straightdope will bring out someone who hates anything you suggest, no matter what you say, Sopranos, too slow, didn’t like Walter in Breaking Bad, Star wars boring kids movie (me!). So any recommendation should be taken as a lot of people liked it. But you might not.
Now, the Leftovers, and why I loved it. I understand if you didn’t.
Season one was a meditation on griefs effects on a bunch of unlikeable people (main family). I say to people give it until the fourth episode before you reconsider, because mostly its people you don’t care about. Once the preacher gets one of his “bad days”, you can see it’s got event episodes which thrill. It’s also a great mystery, all the way through, but without it being shouted at you. Perhaps being left for the 10 weeks it showed made the questions and thoughts stew in your brain, and works less well on a binge watch. Because the main characters are mostly highly affected by the event, but not visibly, and each reveal at the end of the is striking and dramatic, and kind of makes you understand why they are all arseholes… Except Nora. For whom it is clear.
The overall mystery theme of Lost was there, without the meanderings and nonsense. Walt? Bunker? Pregnancies? It was a world of mystery, and had effects, such as what would happen if the supernatural was undeniable, and those who think it god (cults) , dimensions (spirituality) and how authorities react to them.
Freed of the shackles of the book, the second season just took those themes and ran with it. Nothing was predictable. It went all sorts of unexpected directions. Quite a few episodes ended with a total shock. The events leading up to International Assassin episode still stick with me to this day when considered, and is one of the best ending of an an episode ever.
And the third season. I must rewatch it sometimes. I didn’t find it patchy, I knew it was going to go all over the place and delivered on that.
The conclusion to me was perfect. We got an answer. But it was ambiguous if it was true. Up to you to intepret and believe her. A lot of things were left unexplained (never dying?) and I felt happy with that. Let the mystery be.
If you didn’t like it. Fair enough. But I bet you remember a few episodes of it.
