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.
Alternate Character Interpretation: Calypso both in and out of universe. His portrayals vary as does where his powers come from and one's interpretation can come from whether or not one considers the games to be in canon with one another. He's pretty stoic in Black but very hammy in the first game. In Twisted metal 1, his powers came from a demon named Black, in 2 he stole them from the demon minion, in the reboot, the preacher implies that he is the devil himself. His interactions with his daughter seem to cast him as a more Woobie, Destroyer of Worlds, and the control he has over his power of wishes is put into question.
There's also his treatment of Mortimer in Head-On. Was it a genuine Pet the Dog moment, or a calculated move to get rid of a supernatural Wild Card? Especially, seeing as in the second Game, Mortimer actually posed a threat to him.
Then there's his interaction with Mike & Stu in Twisted Metal 2. Did he purposefully trick them into jumping head first off a building, or was he willing to give them the plane tickets just have their disappointment be the deception and he was genuinely shocked at their stupidity? In the first game, he gave Hammerhead's drivers, Dave & Mike, what they wanted without bothering to trick them (be it his harem, or expensive tires, another mundane monetary loss that Calypso could cope with just like the tickets).
Base Breaker: The direction the PS3Revival took for the series; giving more engaging and complex storylines to four distinctive drivers, thus relagating the past drivers to oblivion and making their cars free for Mooks from the aforementioned quartet to drive; this rubs the wrong way for fans of the old installments where one could see each vehicle (and driver) getting a backstory, while others likes only 4 characters getting better developed stories, instead of many drivers getting Excuse Plots to force their presence in the games. However, this does still feel off considering Twisted Metal Black managed to give the characters more developed stories as well as individual cars.
Broken Base: The people who like 3 and 4 against the people who like the rest of the series.
Contested Sequel: Twisted Metal 3 and 4, since they were developed by a different team.
Darkness-Induced Audience Apathy: Sweet Tooth and Dollface's stories in the PS3 rival. The more the story advances, the more the player learns about how horrible both of them are, and has no reason to want them to get what they want. Probably why they end up as Asshole Victims. Although Sweet Tooth hasn't been exactly the nicest guy, it's kinda expected.
The bigger problem is that in the PS3 game, the Story mode consists of only three characters, and they're all evil mass murderers, with no sympathetic or anti-hero characters to offer up as in the previous games. While they all get what they deserve, always controlling a villain really does sap from the experience. Contrast the coolness of Sweet Tooth in Black, where his goal is to toy with and eventually kill Calypso (something the player can rally behind), to the more disturbing version in the following gen, where his goal is to kill his daughter, the "bitch who got away."
Twisted Metal 3 had this problem as well. With Calypso intentionally screwing everybody over in very bizarre ways, there was no point in ever doing the campaign modes for the characters.
Buster Cobb's probably the only Twisted Metal 3 character (or rather, car) that has at least some semblance of fan-following.
Quatro and Orbital are probably the only characters introduced in 4 that fans like, though this is attributed to either making a wish that was worth a damn, or being a Badass bounty hunter that doesn't fall for the traps of Twisted Metal. It also helps that the rest of the cast are, put very bluntly, annoying and cartoonish.
Mr. Ash, the original driver of Darkside, only had a story mode in the original Twisted Metal, but he's still easily one of the fan favorites to this day. It probably has something to do with being actually Satan, and also seemingly the source of Calypso's powers in the first place.
Simon Whittlebone, a frustrated architect who uses an armored and heavily weaponized front loader dubbed "Mr. Slam". to wreak havoc and destruction. Marvin Heemeyer, a frustrated repair shop owner who used an armored and heavily weaponized bulldozer the press dubbed the "Killdozer" to do the same thing in a real life small town.
Game Breaker: Playable versions of bosses tend to be these. There's a reason why they are usually not available at the start of the game, having to be unlocked either through game progress or cheat codes. Twisted Metal 4, however is notable with it's super variants of the previous characters (Super Axel's shockwave for example, knocked all enemies REALLY far away, had 360 degree coverage, and set fire to them as well), or just plain cheap like Moon Buggy's Quasars.
Idiot Plot: Twisted Metal III is the worst offender. Among the wishes of the competitors include; wanting to have a barbecue, wanting to "hang with (his) homies", wanting to party all night long, and wanting people to see (his) inner child. Why in the world would anyone go through a life-threatening contest to get things they could do themselves?
Individual drivers throughout the series often tend to have questionable motivations for risking their lives. Angel, Thumper's new driver from Head-On, is one such stand-out, risking life and limb and leaving a trail of destruction in her wake.... just so Calypso can pimp her ride. It has a freaking flame-thrower, lady, what more can you possibly want!?
Narm Charm: Calypso's voice in the 2012 revival. It's growly as all hell, which is fine, but it's also...a little bit congested. That said, Calypso is hilariously blood thirsty, and the voice just captures that school-boy ant-burning glee so perfectly, stuffed-up-nose and all.
Dark Tooth in 2. The vehicle was a larger, black-painted version of Sweet Tooth's ice cream truck that followed you relentlessly around Hong Kong and launched multiple attacks on you at the same time. Particularly frustrating was that it would freeze you while launching its specials. It even went so far as to launch the Dark Tooth head from the top. When you finally did destroy the vehicle, the head survived and continued the same search-and-destroy method.
Needles Kane in 4 had the Henchmen attack, which sent out three clown heads that followed you through walls, then swarmed around you and bombarded you to death with various stunning/immobilizing attacks. You pretty much had to keep running in a very specific circle around the map, leave a trail of explosives behind you, and pray to god it would kill him before you ran out of road. May be the cheapest boss in the series; this resulted in many thrown controllers.
This was preceded by Moon Buggy in the same game. Quasars, his special, was basically Outlaw's Tazers combined with Spectre's transparent homing abilities. He fired two or three at the player at once. The Quasars also severely disoriented the gamer by throwing the car every which way. Fortunately, it doesn't last exceptionally long.
Both bosses in Black. Minion in particular was a pain, since his shields become very hard to hit when he's down to one or two. Then there's Warhawk, a helicopter that has the unfair advantage of aerial attacks, in addition to the first half of the fight being a Puzzle Boss where you must disable the tanker trucks, which are a Degraded Boss version of Minion, and detonate them underneath him when he flies over the helipad to destroy his shield.
True Art Is Angsty: The best games in the series, Twisted Metal Black, and Twisted Metal 2012 are also the darkest; and fans love them for that, too.
What Do You Mean, It's Not Symbolic?: The fact that Needles and Marcus Kane, despite being split personalities (Needles being a violent, psychotic half and Marcus being his sanity and reason), exist as two separate entities, drive two separate vehicles, and constantly battle each other until the Dark Tooth ending from Head On where Needles and Marcus meet in the middle of a field curious about seeing the other but ultimately decide to work together, resulting in an unstoppable force of destruction.
