So sick of these "Real Fans". Seems like every show's got them, and they all suck. Just because you love something, doesn't mean it belongs to you, or you're somehow more "real" of a fan. These "Real Fans" always think any changes made to their beloved show are an abomination. Hey Real Adventure Time Fan, you know that Fin and Jake story ended right? It was 10 seasons long and wonderful the entire time, up to and including the ending. This is a new story and it's different. Different can be good, and this is good so far. To everyone else, if you liked Adventure Time and aren't an insufferable tool, you'll probably like this. Give it a shot.
