Finally got around to watching the start of the season and this show never ceases to keep me entertained.
Episode 1&2: Finns dad is such a jerk and this probably won't be the last time we see him. The Lytch becoming a baby again was sort of funny. I felt bad that Finn lost his arm (I know it's a kids show and the viewer rating would have to change, but seriously, no blood?!? I mean you show a leg regrowing with all of its blood vessels, muscle, etc or show a man turn to ash but you can't show blood?).
The third episode was mindless entertaining humor.
The only thing I worry about with the series is how chill the series is getting. I get that the creator wants a show about two guys just bro-ing out, but the title of the series is Adventure Time. There should be more of a balance between adventuring and relaxing. Luckily it's only the start of the season so hopefully it picks up some.
