I saw the trailer and thought "Nope, not interested"
I watched it anyways
I watched one episode and thought "This isn't that good"
I continued watching anyways
After a couple episodes I started to enjoy it
I continued watching
Halway through the season now and I actually really like this show. It has some seriously clever humor at times, it just really does have a concept that doesn't attract and the first few episodes aren't good, but if you can get past that it's actually deeper and overall better than most adult cartoons are.
Plus it has a hilarious name. BoJack Horseman. It's just fun to say that.
