This episode got me. I really enjoyed it, although some parts were fairly stupid or boring. The beginning and ending of this episode are the worst part, and the final solution for the two characters adventure is smart but I personally didn't liked it.
The whole story of 7 was interesting, and the whole Jake story was absolute fantastic, though the Finn story didn't got me until the plan scene.
This episode make me smile throughout its running time, and my vote is 8- because it's great but it could be better.
