Alas, Poor Scrappy: Kite/Animus may have been annoying, but his death scene is legitimately sad, especially since it's his human form that we see die, and unlike his Sentai counterpart, we never see him come back with the other Wild Zords.
In the other wiki... "In Wild Force, while Kite was never shown after the final battle, the five Wild Zords that made up Animus were shown to be restored with the others in the final episode, the only hint that the boy had survived." In other words, it's basically offscreen because they didn't show all 100 Wild Zords returning onscreen.
Alternative Character Interpretation: Animus can get hit with a heavy dose of this during his arc. Is he just upset that the humans who were supposed to defend the planet are destroying it instead or is he just an environmental terrorist who has the tendencies of a fascist? When Animus revealed that taking away the Rangers' powers was just a test to see how dedicated they are to protecting the Earth, did he really intend for there to be a test, or did he just say that to avoid getting called out by the Rangers?
Anvilicious: The Animus Arc. The series, despite the whole "Orgs were awakened from pollution" part, played the environmental message a bit subtle until this arc. This arc, in particular the last two episodes, lacks subtlety with Animus declaring humans should be left to die because they don't treat the Earth with respect.
Base-Breaking Character: Cole. Controversy with his actor not withstanding, some think he's a decent character with a compelling tragic backstory, others think he's boring and uninteresting.
Not coincidentally, Merrick (Outside of his acting) is one of the most popular Sixth Rangers since Tommy. Must be the general Badassitude and goatee.
Jindrax and Toxica, due to being actual likable villains with a believable friendship and sense of camaraderie with each other, and they could also be genuinely funny at times.
Epileptic Trees: Danny Delgado has the same last name as the SPD Yellow Ranger, Z. Since SPD takes place 20 Minutes into the Future and Z's parents were canonically scientists involved in creating Ranger powers, people think Z might be Danny's daughter.
For "Forever Red", Disney and Bandai nixed the original ending of all the Red Rangers' zords destroying Serpentera because they didn't want to show "old toys". Not only did Toei have no problem with doing exactly that with Forever Red's closest counterpart (Gaoranger vs. Super Sentai), they did a second time for Gokaiger's 199 Heroes movie.
Speaking of Forever Red, Tommy wears a black leather jacket over his red shirt. And what ended up happening two-years later? He ends up becoming the Black Ranger
Magnificent Bastard: Onikage as his plan involved preparing things for Master Org's return to his throne. Not to mention, he's quite a master manipulator as well.
Mis-blamed: People have noted that a lot of Wild Force's problems are actually coming from a direct translation of Gaoranger, such as the blunt Green Aesop. In actuality, while Gaoranger did have a Green Aesop, it was not nearly as present as it was in Wild Force. Considering that the Green Aesop being Anvilicious has been a problem as far back as Mighty Morphin, it's likely a combination of the existing Green Aesop with the one that's present in Power Rangers being added on top.
Replacement Scrappy: During the six episodes between Unfinished Business and Forever Red, Mandilok takes over as the Big Bad. Compared to Master Org, Mandilok is basically a flat character whose only goal is to just eat.
Princess Shayla, who is basically a really useless Princess who sings. She also tends to be kidnapped a lot. Despite the one time she did something awesome, kicking Toxica away when she had grabbed her by the Standard Female Grab Area and claiming that she wasn't "just" a princess, she is still hated simply because this occurred only once and was never mentioned again, reverting Shayla to the silly Disney Princess role of stand-around-look-pretty-say-"deep"-stuff-and-get-kidnapped.
Kite. A whiny little brat who completely disparages the Rangers' efforts and sacrifices, rants on and on about how Humans Are Bastards, is perfectly willing to abandon them and Shayla to die, hammers in the Green Aesop in the most annoying, tedious and Anvilicious way possible, is of little help when actually needed, and and has an annoying, whiny voice. He was Animus (which makes him a scrappy by proxy), who because of his hatred for humanity who even after revealing that him taking the Zords and the rangers' powers away, and him putting Shayla in a coma was a Secret Test of Character, still didn't take back any of the things he said about humanity.
Stock Footage Failure: When Max faces off with Bowling Org, the scoreboard behind them clearly says "Gao Blue" and "Bowling Orgu."
When Merrick (as Zen-Aku) is infected with the villains' bug, it's not Toxica holding his left arm, but rather her Gaoranger counterpart TsueTsue. It's especially apparent since Sin Wong has a noticeably rounder face than Rei Saito.
Conversely, it's two team ups "Reinforcements from the Future" and "Forever Red" are both so well regarded that later team ups and anniversary specials are compared to them, with the mentioned two being favored over.
Vindicated by History: Much like Turbo previously, this season has become steadily more popular as the years go on (helped by Linkara saying how he thought it was a good season), especially since we now have threeotherseasons that fans like to bash on.
Villain Decay: Remember that HUGE planet-destroying serpent robot that completely dwarfed the other zords and couldn't be fought, only ran away from? Yeah well, now it's about 1/5 of its size, and can be defeated by 1 guy on a flying motorbike. And its planet-destroying laser won't even kill the guy flying inside its mouth. Though to be perfectly fair, this was due to Executive Meddling forcing them to axe a far more impressive Serpentera fight (Which would have had the Red Rangers charge Serpentera all in their own Zords).
To be fair, the only Red Rangers with any zords left were Aurico, Tommy, Andros, Leo, Wes and Eric (excluding Cole who was the active Red Ranger at the time who used his Wild Force Rider). Even then, only Tommy, Andros, Leo and Wes could have zords that can combat against Serpenterra, mainly the Zeozord V, Delta Megazord, Lion Galactazord and Time Flyer 1. The others are not capable of flight and the fact that Jason's, T.J.'s and Carter's zords were destroyed.
Woolseyism: The French dub is mostly good, if corny, which is a given considering that, well, it is Power Rangers. However, this trope gets kicked in the groin in Forever Red. While most of it is fine compared to other episodes, this time, the morphing calls are all translated word for word. For instance, the original "It's Morphin' Time!", which was translated as "Transmutation Demandée" (= "Demanding Morphing") in Season 1 and "Paré au Combat" (= "Ready for Battle") in Season 2 was changed to "Temps pour Morphing", a direct translation that makes no sense at all in French. Same for Time Force's Morphing Call, although it was already butchered in the Teamup. Oh, and Jason, Tommy, Aurico and TJ changed Voice Actors for no good reason.
