is american horror story season 2 (asylum ) and season 4 ( freak show ) worth watching ?

I actually like Aylum best, because it's awkward-horror, rather than just brutal, or grotesque, so it's much more realistic, and therefor much trickier to pull-off.

All of the seasons of AHS are worth watching in my opinion, because they're all high-quality productions, with great actors, and story-line.

Asylum yes but i hate Freak Show

yes

Asylum is really good!
Freak Show, not so much.

Asylum was the best of all

I say watch season 2 and skip season 4.

All seasons are worth watching

In my opinion, they are all worth watching.

The second season takes place in two distinct time periods and so takes a little while to build momentum, and the machinations of the different parties may make it a little hard to follow at first. But, like the first season, I believe it pays off in the end.

The fourth season, meanwhile, was pretty consistent. And despite being the weakest...Compared to Superman, it was at least Goku. If that makes sense.

Asylum was my favorite season out of all of them. It was the creepiest, most chilling season IMO. I loved it. It's the only one out of all of them that I've re-watched. Coven was probably my second favorite after Asylum.

Freak show was my least favorite AHS season. It was watchable but it never hooked me the way all the other seasons have. It was a little creepy but I felt like some of it was just a little slow compared with the other seasons.

Also I actually really enjoyed Hotel, even though it didn't start out too great. It definitely got a lot better after the first couple episodes. Lady Gaga was surprisingly good in the role she played. She impressed me in the later episodes of season 5. So I'd recommend trying Hotel too.

Asylum is widely considered to be the best season, and it has the most consistent and coherent plot. Freak Show is ok, but it resolves its best plot line too early and just kind of limps to the end.
