Maybe they should just put the entire first season as-is in theaters, so that the irreparable harm this movie may have done to what is certainly the best children's show in a long time can be at least slightly mended.

Who was the killer?
Who did crazy hammer guy kill? What did he have to do with Newton? Was Newton at all involved with the initial kidnapping, or am I confused?

That's what she said.

Nothing beats the singing corpses.

Hopefully not the last

@tabernacle, that's a very interesting point. If there wasn't an exchange, could the act of removing Peter have caused the problems of Earth 2? The observers did say he was important; maybe the only way to rebalance Earth 2 is to return Peter.

I was confused too, but when I watched it a second time, just before Peter is knocked backward, the Secretary is shown crossing on to the other end of the bridge.

@tabernacle, I had the exact same thought about Newton. He is the Gordon Ramsey of inter-universe voyages:

On the note of the triangle, I would think that the vertices of the triangles must be in relatively the same place in both universes, and those in Universe B (or the Mongooses, what have you) were placed in somewhat more convenient locations. Additionally, it wasn't exactly difficult to place the Universe A wave…

With a candlesitck!!!!

Frankly, I found the episode fairly entertaining. As for the clock, I didn't watch Lost, but how annoying could a timer in the corner be? I can't imagine that being a serious problem unless some sort of ultimate plot-twisting deus ex machina was shown only in the bottom right corner and then never again.

Minor glitch that I am nonetheless pointing out
When April was watching the show with the opposum that referred to "meerkats," the animals on the television were in fact lemurs.
