I find the show okay and I don't hate the show in my opinion but, the few episodes (Fanboy Stinks, Moppy Dearest, Cold War, Battle of the Stands, Saving Private Chum-Chum, Fan-bidextrous, I'm Man-Artica! and Schoolhouse Lock for example) are not good.
I don't seen all of the second season episodes of the show because, it looks a bit boring and cheesy. Maybe I do not want to watch more episodes of the 2nd season of the show.
I don't see what the problem is with Fanboy and Chum Chum. It uses gross-out humor. So what? Half the shows in the 90s that we all know and love use that kind of humor, and I don't see anybody complaining about those. Ren and Stimpy as well as Cow and Chicken... Both are beloved old cartoons that threw those gross-out jokes in your face at least once every episode. I guess people just aren't as welcoming to gross-out humor as they used to be. That doesn't mean you should be bashing this show for its style. If anything, I just see it as a way to reconnect to the 90s style Nick. Now if you feel like throwing out some random insults or bashing this show for no legitimate reason, go ahead, but just know I'll ignore you. On the other hand, if you actually do have some constructive criticism for your dislike on the show, feel free to share.
