Corrected entry: When Korra gets her bending back, she ends with a massive wave shooting up over the cliff. But there is a difference between the shape of the wave between the two shots: in the first one, there is a sort of notch, through which we can see Korra, but in the reverse angle, the notch is instantly gone, it's just a wall of spray. (00:21:05)
Corrected entry: When Korra parked the car, she ended up bending a lamppost. Those are pretty tough, but there isn't so much as a scratch on the bull-bar of the car. (00:08:15)
Correction: First, "there isn't so much as a scratch" is wrong; we don't know if there was or wasn't a scratch, because the part that gets scratched was not shown. Second, "those are pretty tough" is a personal assumption. (I assume from the real world?) A car is shown to have bent a lamp post. That's evidence that lamp posts in this cartoon world (which is a steam-punk world) are not tough.
The Spirit of Competition - S1-E5
Corrected entry: In round three of the last match, Korra opens with dodging an earth disk. This one was going to hit her in the head but it wasn't called by the refs.
Correction: 1) That is exactly how it is intended. The white portion of water gets sprayed. The blue portion goes back down. It is unsurprising, especially because Korra is emanating a shockwave. 2) I can see two notches going back down.
