Letting Off Steam (Thomas & Friends: All Engines Go!)

Plot
Thomas and Percy get into their first major argument and think their friendship is over.

Why It Needs To Let Off Steam

 * 1) Thomas gets into a fight with Percy just because he laughed at him.
 * 2) "It rehashes Thomas, Percy and the Coal" from Season 2 of the original series and the Railway Series story "Drip Tank" from "More About Thomas The Tank Engine".
 * 3) As usual with the songs of this show the song in the episode is really annoying and cringe-worthy.
 * 4) Their arguments are really pathetic and laughable. You could argue that they are meant to be child-like in the reboot, but even so, them being kids still misunderstands Thomas & Friends as a whole and what made it iconic in the first place.
 * 5) There's a scene where Nia has Carly's horn despite the fact that she's a steam engine and shouldn't have a horn.
 * 6) As usual, the animation is pretty mediocre with quite a few errors.

Redeeming Qualities

 * 1) Gordon is the only likeable character.
 * 2) Edward and Henry make cameos.

Trivia
