Episodes you think are underrated?

Kanto:

"The Tower of Terror"- Does not get enough credit at all, was a really great episode- had comedy with Haunter & Gengar, sad moments like Ash dying after the chandelier fell on him and his soul leaving his body, and it ended well.

Orange Islands:

"The Rivalry Revival"- Perfect way to end the Series before Johto began, simply perfect. Ash still having a lot to learn after his loss to Gary here, then being motivated to continue by his friends, Brock rejoining & Tracey leaving, Prof. Oak giving him a new goal w/the GS Ball (sadly went nowhere!), and Delia doting over him before it ends (I refuse to use "The Beginning" as a label for this and Kanto, absolute TRASH re-branding, "Adventures in the Orange Islands" may not be anything stellar but was FAR less bland and generic).

Johto:

"A Parent Trapped"- This is how you do drama correctly in this Series, very believable subplot with every character having purpose. And hey, JCC using the voice he'd later recycle for Prof. Oak in Dr. Namba, only it actually FITS a mad scientist!

Hoenn - Battle Frontier:

"A New Land, A New Adventure/Get the Show on the Road!": A very sad opening cutscene (Pikachu gravely ill), a far more dramatic + sadder subplot (Ash has to rescue it before it's too late, almost dies jumping off the cliff but barely makes it by grabbing on to the tree branch last second, electricity overload for Pikachu via the electromagnet prior in "Hoenn Alone"), and lastly, a far more convincing ending than many of the later restarts in regions would feature for the rest of the Series.

"The Scheme Team"- Everything about this was well done, how Ash met Agatha, how TR interjected, how he battled the last member of the Kanto Elite Four at last he never did prior, and lastly, meeting Scott to start the BF saga.

("Time Warp Heals All Wounds" is ruined for me, by the dub in which Michele Knotz is practically moaning/groaning through all her lines as May for me w/a sullen timbre too, it MIGHT'VE made it had the original 4Kids dub lasted into BF though past the Battle Factory: an example of how the terrible, terrible dub change killed something for me that I might've otherwise liked in English- in Japanese, sure, it's good though)

Sinnoh:

Nothing, in fact, most are overrated with "Pika and Goliath" being a cheap knock-off ripoff of "Electric Shock Showdown" earlier on IMO.

Unova:

"Ash vs N, A Clash of Ideals!"- A nice subplot where Ash begins to be less stupid than he was in most of the rest of the saga and makes friends with the Mysterious N, who has an intriguing story to tell at the time.

Kalos:

THE most overrated saga, period, with "A PokeVision of Things to Come" being one of the absolute worst episodes of all time too.

Alola:

"One Journey Ends, Another Begins" is pretty good, especially considering how overly goofy and comedic this saga could get, not often is it that Sarah Natochenny and I agree on much of anything but I'll give her and Lisa Ortiz this-- this is the type of episode that is what some people liked about the older Series more, a sad story with a convincing tale to it (Stoutland dies).

Galar:

Nothing comes to mind- while this saga gets slammed by most of the modern fandom as the nadir of the Series along with Johto and BW, that said, I would take a lot of the episodes here over the extremely overrated and undeserving of the praise given to them DP & XY personally (especially the latter).
