I watched it a few months ago and got a kick out of it, especially the Hollywood jokes (we're probably less than 5 years away from a gritty, amped-up update of Huckleberry Finn). I couldn't give two shits about the romantic subplot and I'm not sure how they can stretch the premise into an entire season, but I'll definitely be watching when the rest of the episodes hit!
The live action Tick pilot from the same Amazon pilot season is pretty good too.
