Alternate Character Interpretation: When her interactions with her mother are taken into consideration, along her general lack of success, Divatox comes across less as someone who willingly went into a life of evil piracy, and more someone who was forced into it, regardless of her actual skill.
Anticlimax Boss: Maligore. An ancient god of evil...who gets exploded with one non-powered slash.
Likewise, the changing of the guard from the old team to their replacements, which comes out of absolutely nowhere, none of the new Rangers are seen having any reaction to the offer. They just literally show up and the audience is told "these guys are the Rangers now". And then the next episode has them as fully established as a team, with no teething period whatsoever.
Broken Base: Some people still claim this is the worst season even though arguably, there have been worse seasons since (Operation Overdrive and Super Megaforce in particular are often seen as having taken the Worst Season Title). Some people agree that while the first half was pretty bad the second half was an improvement. Others believed the first half was bad but the second half was even worse for changing the entire cast save Justin (who was decidedly unpopular). However, most can agree that the first 19 or so episodes of Turbo weren't Power Rangers' best.
The ending is a bit of a mixed bag in itself. Not because it was bad at all. On the contrary, it's considered by many to be the best moment in the entirety of Turbo due to just how harsh and intense it got, what with the Command Centre being invaded by an endless wave of mooks then ultimately destroyed (for good, this time), and the Rangers, now powerless, have to set off into space to find Zordon whilst leaving one of their own back on Earth because he's just a kid. The problem is that it's ultimately Divatox who succeeds in bringing the Rangers down to their Darkest Hour after the efforts of more competent and serious villains like Rita, Lord Zedd, and the Machine Empire.
In real life, Blake Foster, who played Justin, is known to be a pretty nice guy and doesn't regret his time on Power Rangers. As he put it in a convention appearance, "Who didn't want to be a Power Ranger?" He also kept his Blue Ranger costume and helmet.
In show, Phantom Ranger, due to how frickin' mysterious he is. So much so, that Phantom got to the final round of the Morphin' Madness fan contest.
Growing the Beard: The additions of T.J., Cassie, Ashley, and Carlos on-screen, with Judd Lynn taking over writing duties more-or-less concurrently. The new characters and more consistent writing gave new life to an otherwise moribund series. After these changes, the ratings saw noteworthy improvement. Looking back, the second half of Turbo gets a far more favorable reception than the first half.
While Power Rangers in Space is given credit to being this for the franchise as a whole, arguably the second half of Power Rangers Turbo laid the groundwork.
Harsher in Hindsight: The episode with the Robot Rangers ends with them going to defend Eltar. As in the Eltar that gets attacked and conquered by Dark Spectre. The inevitable conclusion isn't pretty.
Ho Yay: Carlos with T.J, Justin with Nico. Cassie and Ashley also got some Les Yay in.
Inferred Holocaust: The brief shot of Eltar under attack in the finale appears to show it being nuked repeatedly. And then there's robot Rangers and Alpha 5, who were on Eltar at the time, and were never heard from again.
Irony: Although it wasn't responsible for saving Super Sentai (despite what the rumors say), Carranger was the first series to end with higher ratings than the previous one. Turbo, on the other hand, had such poor ratings that it almost killed the franchise.
Memetic Mutation: They were baked into a giant pizza. This is among the most remembered parts of the season.
To the point of being brought up in "Forever Red".
Mondegreen: It's not unreasonable to assume the theme song talks about "trifle on the floor" in the first verse.
Never Live It Down: Getting baked into a giant pizza. Though in the team-up "Forever Red", T.J. did kind of take it in stride, bringing it up in a bit of Self-Deprecation humour, much to the chagrin of the other Red Rangers (except for Cole, who was quite curious to hear the tale) who are implied to have heard T.J. telling them the tale so many times already. By playing this for laughs, it's highly likely that the writers and producers did feel a little badly for having the infamous pizza episode; and so, through T.J., they wanted to make up for it and poke fun at themselves for it.
Replacement Scrappy: More or less averted since its generally considered when the new team took over the writing improved. Though there is still a vocal minority that hates the team simply for replacing Fan Favorites Tommy and Adam, though even then most of the detractors learn to like the new team by Power Rangers in Space. Not because the characters changed mind you, simply because that season was more well received.
And it didn't help at all when we learned the producers didn't even have the decency to tell their long-time stars that they'd been fired, and they had to hear about it through gossip from the hair and makeup people.
The Scrappy: Too many, which is why this series is disliked.
Justin, who had shades of the Creator's Pet. But a lot of it comes mostly from concept rather than execution. He was a young kid compared to the older Rangers and no matter how hard Blake Foster tried he always stuck out among the group. But as a character he was fairly well rounded: skilled and observant but with moments of jealousy, pride and short-sightedness.
Alpha 6, also of Turbo, could qualify. While Alpha 5 was dorky-but-lovable, Alpha 6 was an attempt to make Alpha cool by using forced-hip slang ("Yo, Rangers!"). It's no coincidence that as Turbo ended, he was damaged, and his voice chip needed to be replaced with one like Alpha 5's.
Elgar, mainly for being obnoxious and not remotely threatening.
Divatox is this due to being a comedic villain and the fandom's general aversion to funny villains for some reason. She also likes to set explosions all over the place and ALWAYS setting them for an hour, enough time for the Rangers to get rid of them!
There are many fans who dislike Ashley simply because of her actress, Tracy Lynn Cruz. She had dated Johnny Yong Bosch and in an interview years later he said once she got on Turbo she dumped him, stole his money and his car. Johnny (and Adam) was already The Woobie to fans and some people paint Tracy as evil, saying that she "eats the skulls of babies to survive". Johnny appears to regret letting out that information, due to how bad the backlash got.
T.J. and Carlos aren't hated, and they are actually likeable characters. But the fact that they replace Tommy and Adam doesn't please many fans at first. But at least, they do grow into good characters on their own rights.
Star Trek Movie Curse: This season starts the trend Power Rangers has where anniversary and milestone seasons have a bad reputation (Turbo- 5th season. Wild Force- 10th season and first Disney season. Overdrive- 15th season. Samurai- Saban's return to the franchise. Megaforce-20th season). Why this seems happen to anniversary or milestone seasons is beyond us, so of course jokes about anniversary/milestone curses are bound to pop up. These seasons are either considered divisive and/or "Man, how unfortunate, they had a lot of potential..." (Turbo and Wild Force come to mind), or they are just considered outright TERRIBLE (*ahem* Overdrive and Megaforce).
Stock Footage Failure: Several members of Divatox's supporting players were redesigned to be much less sinister looking, making spotting the Carranger footage pretty obvious. Especially◊ Elgar.◊
They Wasted a Perfectly Good Character: General Havoc came off as a far more effective and interesting villain than Divatox, but he just disappeared from the series and only made fleeting appearances in the next series. Some feel that when he was introduced, he should have taken over as the Big Bad.
Villain Decay: Divatox was competent enough in the movie. In the show? Not so much.
Finally inverted at the end when she led an army to the power chamber and utterly destroyed it, and she probably would have killed the rangers (once she discovered they survived) if she hadn't been summoned away
Vindicated by History: Sort of, because it still has a wide spread Hatedom among some people still wearing Nostalgia Goggles who just remember it as "the season that got rid of Tommy and Adam". Other than that, however, the reception was a lot warmer in the second half of the season than when it first aired, helped by the fact that the writing actually improved and that there has been arguablyworseseasons.
Again, it didn't really help matters when the source material it was based on was actually a self-parody of the Sentai series, so when they tried to make it more "serious", of course they would run into a lot of problems (with the pizza-episode being the most infamous one). Eventually, they managed to work around the source material half-way through the season; but who knows how the series could have turned out if they had just taken the risk in the first place of poking fun at themselves (in a lighthearted sort of way), writing the slapstick and the comedic/satirical elements in a way so that it is tailored for an American youth audience, and not taking themselves too seriously...
