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: Phantom 2040
Seasonal Rot: In what is possibly one of the quickest onsets of this trope ever, the latter half of the second season is noticeably more episodic and less well-written than the rest of the series. The series finale in particular feels rushed and incomplete. This was caused initially by Executive Meddling trying to make the show more accessible to kids, then by the show's production staff learning that cancellation was imminent and scrambling to give the series a proper ending. Despite this, many still consider the series to have been Too Good to Last overall.
At least it got a proper ending. That's a lot more than can be said for many other series that faced similar circumstances.
