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: Resident Evil 5
Base Breaker: Sheva generally is very polarizing with most Resident Evil fans. To some, she's a typical bland, one-dimensional, and uninteresting character whose main purpose in the game is to be Eye Candy and to push the new "partner" system in the game (which, judging by how the AI was negatively received, failed in that regard). A large number of fans also were quite disappointed she got to assist Chris in finishing off Wesker; an honor that many believed she was undeserving of and should have gone to Jill. There's also a few who believe she was created simply to respond to the racism allegations surrounding the game before release (and even in that regard she's controversial). On the other hand, Sheva also has a few supporters who liked her characterization as a loyal soldier who had been pushed into a situation that was way over her head. She is completely locked out of Chris and Wesker's history and provides a fresh perspective against the monsters that Chris is so jaded with fighting.
Two on Two, played during the fight with Wesker and Jill.
Demonic Spiders: Lickers, as par for the series' course. Their regular claw attacks pack quite a punch, their tongue spear holds its victim in place, perfect for others of its kin to start a Cycle of Hurting, and if you miss the button prompt that repels their leap attack, you are guaranteed to die unless helped by your partner, no matter how much health you have. To put the cherry on the cake's icing, they always show up in packs.
Reapers. Giant, vaugely humanoid insectoid creatures that resist most of your gunfire, regenerate what you can damage, including their heads, spew noxious gas, and have a very tricky weak point that you need to hit. The best part is that they have a One-Hit Kill. If you get close to them, they will kill you, full stop, no calling for help. As bad enough as this all is, it gets worse playing on single-player, when Sheva decides the best thing to do is to rush in and close the distance.
Disappointing Last Level: Chapter 5 and onward start throwing more cheap deaths and frustrating enemies (such as the aforementioned Reapers and Lickers) at you, with the enemy base ending up rather generic and flat in comparison to the somewhat lively and creepy villages and jungles the game used previously.
Josh Stone is becoming quite popular since the game's release. Reasons include his accent, his knack to save Chris and Sheva multiple times, especially from Jill Valentine, the spectacular wrestling moves he performs in the Mercenaries Reunion Mode, and the fact that he's the only minor character in the whole game that makes it out alive and was there to save Jill Valentine after she was released from Wesker's mind control and piloted the helicopter to rescue Sheva and Chris along with her. By the way, did you know that he's A LEGEND!!!
Doug the helicopter pilot from the Desperate Escape DLC actually has a recently growing fan base. His Tear Jerker death certainly helped play a large part in this, as he's another sad victim of the curse of dying helicopter pilots in the series.
Ricardo Irving was seen as a spiritual successor to Ramon Salazar and has a large fanbase.
One of the series' long standing Darkhorses, Barry Burton, was brought back for the Mercenaries Reunion solely because of this reason. Same applies for Rebecca as well.
Fanon: A lot of people assume Sheva is meant to be mixed-race, mostly due to one of her outfits being a shout-out to Halle Berry's character in Film/Swordfish, but nothing is said about her parents' ethnicities one way or the other. Her motion actor is Dutch/Indian.
S.T.A.R.S. Wesker in The Mercenaries is just one example. On the other hand, Midnight Wesker is das professional character, meaning he has all that is needed for overinflated combos and scores, but you need to be good.
Rebecca. Yep, that◊ Rebecca. With an auto shotgun that can one shot most enemies and a MP 5 for long range work, a good player can kill everything before time runs out.
Giving A.I. Sheva a SIG P226, especially once you upgrade the damage to 480. Sure, she focuses on her handgun, but if you're playing on New Game+, you've probably got a decently upgraded AK47 which can do double duty for pistol-style work against enemies anyway. And AI Sheva is a dirty, cheating A.I. on your side, able to two- or three-shot most standard enemies at an absolutely ridiculous range right up until Licker Betas and other high-HP enemies start to appear regularly.
The Rocket Launcher can become this in a flash in story mode if you unlock infinite ammunition for it. Sure, it requires you to beat the game first, but you can unlock the good stuff on Amateur difficulty and proceed to one-shot bosses even on Professional.
In a Co-Op session, one player can give a human partner stuff (weapons, healing items, rotten eggs, etc.), have the player with the donated goods to quit the game and save what they got in their inventory while the other player does not save what's lost at all. This results in items being duplicated, making it quite easy to rack up money, especially from valuable equipment. Xbox 360 players can easily do this with just two gamer profiles and two controllers; PlayStation 3 player don't have the same game-breaking luxury as they require another player online to duplicate items.
Goddamned Bats: Adjules. They don't inflict or sustain that much damage, but their speed and low stature mean that you will likely waste a lot of ammunition trying to hit them.
He's Just Hiding: Countless fans don't buy the apparent Word of God that Albert Wesker is dead and insist that for now the character is retired, but believe he will one day return. Considering the creation of Jake Muller in the sequel and the mysterious Alex Wesker, it's clear for now Capcom now sees the gravity of their mistake killing him off early and tried to compensate for one character with two.
Chris says "Do you take all of your ideas from Comic Book Villains?" to Wesker, then, it turns out that Wesker and Dr. Doom are teaming up inMarvel vs. Capcom 3.
The same line also becomes hilarious with the release of Captain America: The First Avenger and its climax, where its main villain, Red Skull (himself a Comic Book Villain), enacted a very similar plot to Wesker in this game, complete with a large bomber jet and delusions of godhood.
Scrappy Mechanic: In Mercenaries, have fun being randomly grabbed by Majinis while you are desperately trying to keep your combo up. Bonus points if the Executioner is around.
Scrappy Weapon: Proximity Mines. Though they have some use in Story mode (usually by leading bosses and strong enemies on them), in Mercenaries they are next to useless since you need to do melee anyway and you can't even use them to clear the mob in a pinch. And in Versus, if you happen to be seen placing them, the enemy player can detonate them by shooting while you are still close. This added to the fact that good players won't be caught stepping on them anyway, since it's easy to tell the set mines from the dropped ones. Further, they only sell for 30 even though they cost 1500 to buy, making them even more of a waste of time.
On the other hand, a strategically-placed proximity mine can kill large groups of Majini at once in Mercenaries.
Ndesu, aka El Gigante of Africa. You are caught in an immobile truck, and the only ways to not be hit are to either shoot him enough to stop him or hit the action commands that flash for a split-second. You need to concentrate fire on him (unless he tosses a hard-hitting boulder) while keeping an eye out for action commands. Random enemies like to come throughout the fight and shoot you with flaming arrows or molotov cocktails, and you can't even heal yourself if your health is too low! This is just a midgame boss, even!
Fights that aren't exceptionally difficult normally become ridiculous on Professional. Irving's tentacles become one-hit kills, and the window for the dodge command is buggy and sometimes lasts less than a half-second. The Wesker+Jill fight is even more absurd, at least on single player. Normally, the enemies on professional ignore your partner for the most part and focus on you, but Wesker and Jill ignore this entirely. Your partner will die, A LOT. Two of Jill's SMG bullets will kill you, and it's almost impossible to incapacitate her in the first phase, as your partner refuses to help after you restrain her. Once you get to the second phase, your partner will run off to try to knock out Jill, but will usually just get SMG'd or smacked by Wesker.
The chase sequence leading up to the Ndesu battle. Enemies have an extremely annoying habit of nailing you from behind with highly damaging Molotov Cocktails while you're busy fighting off armored trucks, there's no way to heal the damage you take on, and it's far too easy to lose track of your tiny, faintly red aiming reticle against the predominantly orange and brown backdrop.
Any level which requires splitting up for extended periods, making one partner useless, or any level that utilizes Hollywood Darkness.
The Scrappy: As mentioned under Base Breaker, Sheva's not too popular in many circles of the fandom. Many feel she was only in the game to push the new "partner" system, and even then, her AI in the game was poorly received. Others felt she was just a generic and bland character that was nothing more than Eye Candy and Ms. Fanservice. And others believe she was shoehorned into the game by Capcom to waylay the Unfortunate Implications the initial gameplay footage (which only featured Chris) brought up. Not to mention she stole the spotlight from the far more popular Jill Valentine and had a hand in Wesker's death that clearly wasn't well received by many, who felt the deed should have gone to Jill, who had more history with the villain.
RE5 actually does a lot to defer that accusation. Your partner is black (a bit), quite a few whiteys are scattered throughout the early hordes, and real effort has been put into a somewhat realistic and sympathetic depiction of modern Africa. And then...! Halfway through the game, we suddenly find ourselves in a succession of mud hut villages fighting crowds of jabbering black people in loincloths and war paint, chucking spears. Oh, dears!Talk about sidestepping a pothole only to fall off a bridge.
Villain Decay: For almost the entirety of the series, and most of the game, Wesker, being the resident Magnificent Bastard of the franchise, seems to be the exact opposite of this trope — until his motives are revealed to be nothing more than generic Social Darwinist bullshit (influenced by Spencer). Chris even calls him out on it, saying that "He's taking his plans from comic book villains". This is Hilarious in Hindsight now that Chris AND Wesker will both be in a crossover with Marvel characters. Funnier still is that Wesker is in cahoots with Doctor Doom, so Chris may as well have been prophetic.
