I had not seen this thread, but I watch a lot of shows so bear with me while I stand on my soapbox.
Game of Thrones I suppose there's not much to say here. I've loved the show from S1. Great acting, dialogues, action, drama, excellent production values, with every season raising the stakes in terms of the story. Sure, S5 was a bit of a drag, but after 4 seasons of excellence, I guess I can cut them some slack.
House of Cards Another example of almost flawless acting and writing all around. It's great to see a take on the back-alley corruption of politics, but it's better when Kevin Spacey delivers it with his scenery-chewing wickedness. The last season pushed the brakes a bit, but it was still pretty good.
The Americans Yes, believe ShadyCrow. This show is damn good. It starts a bit on the "just okay" side, but once it finds its stride, it delivers in almost every aspect. Great performances, good script, solid directing. Every season, the cast and crew have found ways to polish themselves, and improve on everything. There are some loose or weak strands here and there, but nothing that really detracts a lot from the whole.
Hannibal Beautifully icky, and perfectly acted, this show managed the impossible by successfully separating itself from its predecessors. Kudos to Mads Mikkelsen for taking the impossible task of not filling Anthony Hopkins' shoes, but rather sweeping them away to wear his own shoes. He's perfect, and so is his partner, Hugh Dancy. But the star here are those visuals, beautiful yet gross, surreal. It's a shame it got canceled. FWIW, I still haven't caught up with S3.
Vikings Of all the shows on this list, this is probably the one that pisses me the most; and it's not because of what they do, but because of what they could do with it and don't. The show has some great actors and insanely good production values, gorgeous direction, and still the script doesn't live up to that potential. Let me rephrase that a bit, the script and story is pretty good, but I always get that feeling that this could be soooo much better if the story was a bit more polished. But it is still a pretty good show that deserves more praise and attention.
Manhattan Yet another great show that deserves more attention. Started last year and I was caught off-guard by how good it ended up being. Great acting by almost everyone, great set and costume design, and a really interesting story to boot. It deserves to be checked out.
Better Call Saul Count me among the skeptics when this show was announced; but after S1, I was a believer. Vince Gilligan manages to convey that Breaking Bad vibe, but without sticking to close to it. The show is its own animal, carried beautifully by Bob Odenkirk. The way the story unfolds was great, to the point that during its run, it was the show I was most looking forward to each week. The kind of show that made me giggle at how good and enjoyable it was. It is obvious they're still working out the story, which was more notable in Nacho's role which felt abruptly undercut, but I don't care. I'm set for S2.
NCIS Yeah, I'm a fan and I'm still on my 30's. Got hooked up with it after watching reruns on cable, and it soon became a personal favorite. I love the chemistry between the leads and the light approach to the stories. I also love how despite being labeled as a procedural, there are countless of subplots that are being carried, even from S1 and on. Love that continuity. It's not perfect, but it's a lot of fun.
Homeland Ahh, the times when this was a promising show. Let's be honest, this is but a shadow of what we got on S1, unfortunately turning into the bastard brother of 24, but without the self-awareness. I still enjoy a lot of it, but I wish they would've stuck to what they had.
The Walking Dead sigh similar to Homeland, this is a show that has strayed so far. The writers still manage to come up with some gems within each season, but for some reason, they can't be consistent. Plagued by mediocrity and a weak pace, I wish they were more bold with their stories.
Bates Motel Similar to Vikings, although to a much lesser extent in terms of quality, this is the kind of show that seems to have lots of potential, but fails to live up to it. Both Freddie High more and Vera Farmiga are great in the lead roles, but there is a lot of mediocrity surrounding them. Some weak scripts, eye-rolling dialogues, and bad performances here and there... S1 started shaky but ended up solid, S2 had its ups and downs but found its way out, S3 followed the same path, but still there's something enticing about it. It's flawed, but worth a shot.
Tyrant I almost gave up on this one. First bunch of episodes were borderline bad, in terms of acting and dialogue, but for some reason, I stuck with it. And then, something clicked in the story that led to an interesting run towards the end of S1. I still haven't been able to catch up with S2, but I'm looking forward to where they pick things up. A very flawed show, but interesting enough to keep me coming back.
The Last Ship Not much to say about this one. This is mindless fun. Lots of action, but it's well directed and the performances are solid enough. I just watched the first episode of S2 and it was pretty kick-ass.
Falling Skies The lesser of the bunch. A very mediocre show and yet very earnest. There are a lot of weak performances, subplots, dialogues, special effects. Men, but there's something enjoyable and fun in it. They're in the final season, but haven't been able to catch up though.
And I started Hell on Wheels about a month ago, but I've only watched 4-5 episodes. Too soon to have a verdict, but I'm liking it a lot.
...and that's me off my soapbox.
