Loved The Office. I caught up when there were only three seasons and watched it straight to the end since. Despite very terrible decisions with story arcs and character developments post-Michael, I never wavered and watched till the end. What I really hated was Pam being painted as a villain later on, despite the course-correction afterwards.
I watched Season 1 of Parks and Rec in its entirety and it didn't really click with me since Leslie seemed too much like Michael Scott, but I've seen it in bits, and I liked what I've seen, though I haven't seen Season 7. It's on my list of things to watch. What stood out to me was how the show changed from an Office clone to really its own thing. I actually wonder if breaking off from the Mockumentary style would've been even better for the show.
I missed the first couple of seasons of 30 Rock, but I watched a majority of its episodes after. It remained consistent for the most part.
Arrested Development is fucking great.
Louie is also great, but I stopped watching after season 4.
Master of None is one of my favourite shows from last year, but I think it needs more than the first episode to really be judged accordingly. I certainly didn't take a liking to it until the second or third episode. The show also introduced me to Father John Misty.
Always Sunny is something I will watch someday. I want to watch it if only to understand the references made here on GAF.
Going back to The Office, I've only seen a few episodes of the UK version. I thought they were good, and I like that the series is only two seasons long.
I've seen one season of Extras, but it's one of my favourites. Highly recommend this.
And on the trail of Gervais/Merchant shows, I do recommend Stephen Merchant's solo outing of Hello Ladies. Unfortunately short-lived, but that might actually be a blessing for it. It's only 8 episodes and a movie, so not much commitment to make for it.
I quickly caught up with You're The Worst, though I haven't been able to watch the third season due to being away, but I do recommend that as well.
