These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: IGPX Immortal Grand Prix
Crowning Music of Awesome: A majority of the music is provided by the British indie label NINJA TUNE. Their music is fantastic. Even the orchestrated pieces.
Grown the Beard: Season 2 is when the writing, mecha action, and characterization improves vastly.
Les Yay: Just a bit between Amy and Liz, especially in one scene in the second season that looked kinda like they were going to kiss.
