My ex and my current girlfriend are both obsessed with AHS, so I've had to sit through a few of the seasons. The first didn't really make sense, considering one of the biggest points of the story is that the spirits who reside there never leave the house, even though it clearly showed Tate at the beach early in the season. The camera work pissed me off, it made an otherwise decent storyline seem choppy and rushed.
The second season I didn't watch entirely, but it bored me. Only thing I remember is being confused at why a guy decides to be an evil bastard because he has a small weiner.
Never saw Coven.
Freakshow was good, I actually liked it. It was still rushed, but not nearly as bad as the first. Only thing that I thought was real weird was how Jimmy hated the Strongman guy who turned out to be his dad because he was responsible for the death of his friend, but once he learned he was his father all along, they just never brought it up again, even though it was his central motivation for the longest time. Loved the ending, though.
Hotel is alright. Kinda confusing (what a surprise) but it's decent.
Walking Dead is the closest thing to a horror show I watch, but it's more of a drama now. Really loved the 6th season so far. Best one yet easily, even if they did waste two damn hours explaining Morgan's past.
