The only worth watching season is the first one. The storyline is simple but super effective. I find the first 3 minutes of the series the best reason to give the series a try.
The second season lack of development in my opinion. It felt rushed, the characters weren't as endearing as in the first. It's good, but is like what happened with the second season of Stranger Things: we know is good, but the first one is so much better.
