I was automatically drawn to this show. Maybe it was the uncanny similarity to Songebob, or just the pure randomness featured in the show that has me watching it whenever it was on.
Fish Hooks is, however, not my favorite show. After a while, it can become a bit annoying, and some of the original charm and appeal wears off. Milo can be extremely stupid sometimes, which doesn't help anything. Clamantha, on the other hand, is plain creepy.
But there is nothing inappropriate about the show. I just love how some people can find something inappropriate about anything and everything, no matter how insignificant.
