[7.3/10] This one got a little plotty for my tastes, but has some cool moments. I like the idea that being from Lumpy Space, LSP is made up of the constituent parts of the elements and so is thus immune to them. Sure, it’s a bit of a handwave, but it works well enough for what the show’s going for.
And I’d be lying if I said I wasn’t affected by Finn eating the bit of bubblegum and seizing on his happy memories. It’s interesting that they’re his best moments with PB and, to a lesser extent, Flame Princess, and that it’s enough to snap him out of being Flame Finn and back to being good-natured Human Finn.
Elemental PB’s “I love you” song, turning everyone into candy zombies, is nicely creepy, and Betty’s doublecross is predictable but still cool.. Again, I’ve kind of enjoyed the development of this one more than the climax, but there’s cool stuff going on, so I’m tempted to give the raw action/convenient immunity stuff a pass.
