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: SWAT Kats
Alternate Character Interpretation: Despite her competence (compared to Manx, anyway) Callie sometimes seems to exist just to be the SWAT Kats' cheerleader and remind everyone how awesome they are. She ignores all their (admittedly mostly unintentional) screwups and constantly obstructs (or tries to obstruct) Commander Feral, who—for all his bluster—really does have the city's best interests at heart.
Animation Age Ghetto: The show suffered from this hard, and it was ultimately killed by the attempts to break out of it. Some episodes make it clear the Brothers Tremblay had in mind something more complicated (and probably something that didn't involve anthropomorphic characters) when coming up with the show, and that the need to write for kids kept holding back what they could do. Ultimately, they pushed the line too far, such as Feral in no uncertain terms killing the Metallikats directly (if temporarily) and giving a rather irrefutable explanation as to why he did so.
Better on DVD: The Warner Archive began offering "made on demand" DVD sets in December 2010. While most of the episodes were not remastered or restored in any way, two episodes did receive a small boost: "The Giant Bacteria" had a deleted scene featuring a farmer being eaten by the titular monster reinserted, and "The Pastmaster Always Rings Twice" finally got its Episode Title Card back after it was absent from practically every rerun.
Big Lipped Alligator Villain: Chopshop. In a world populated by nothing but anthropomorphic felines, Chopshop is a... laughing hyena? In true BLAM fashion, he shows up for about five minutes at the start of the episode "Swat Kats Unplugged" until he's captured, and is never heard from or spoken of again in the run of the series.
Just because T-Bone called him "a laughin' hyena" doesn't make it true. It's doubtful the writers would introduce a non-cat that wasn't an alien so late in the series, and have him be a nothing villain like Chopshop.
The Firefly Effect: An extremely rare case of inversion of this trope. The effect usually takes hold in three stages: the show suffers from Executive Meddling, which results in low ratings, which results in getting Screwed by the Network. SWAT Kats—in spite of the meddling—went on to get high ratings, then got cancelled in defiance of the ratings.
Foe Yay: T-Bone and Turmoil have this going on big time.
Germans Love David Hasselhoff: This show has a very vocal fan following in India, where it was one of the first few shows that appeared in 1996, when Cartoon Network was launched. Plenty of Indian fans discuss this on forums, social networks and upload videos on YouTube.
Harsher in Hindsight: The SWAT Kats flying the Turbokat into a building to save Callie. Doesn't help that said building immediately after explodes.
Only because the villain threw explosive chemicals. A better example are the Megakat Trade Towers, which are featured prominently in "Metal Urgency" and are seen briefly in "SWAT Kats Unplugged". Both times, they're at least partially damaged—and in the latter case, they appeared to be the deliberate target of the evil helicopter pilot the SWAT Kats are chasing at the episode's start.
