There are subjectives, and then there are these. While you may believe a work fits here, and you might be right, people tend to have rather vocal, differing opinions about this subject. Please keep these off of the work's page.
BioWare really does need to work on picking its trailer music. And not just trailer music, either. This Is War by 30 Seconds to Mars in the end credits of a fantasy game? Airy LOTR-esque soprano in a sex scene? It just doesn't work.
Leliana is supposed to be a bard, so she must sing at some point. However, both the buildup to the scene and the execution leave a lot to be desired.
When she uses any of her song abilities in battle, she appears to lean her head back and howl.
She doesn't mysteriously change voice actress, either.
She's not singing - it's her old elven nanny's voice.
If you make the other rogue characters into bards, you'll learn to appreciate how good Leliana's battle cries sound. Nathaniel's bard cry is akin to him stubbing his toe. Zevran, meanwhile, holds his scream for way too long.
In one area, you're asked to help stop a group of werewolves who have recently attacked a group of elves. When you talk to the elves, you are asked by one man if you would look for his wife, who he believes has become a werewolf. When you find her, she's is, in fact, a werewolf, and is obviously in a great deal of pain and doing her best to fend off the savage nature of the werewolf. She asks you to kill her to make the pain stop. The voice acting and storytelling are both handled in such a way that this is actually quite a moving moment . . . until a moment after she is dead, at which point you realize you can loot the corpse. FOR A WEREWOLF PELT.
Whenever you are given an option to kill a character in a cutscene (with the notable exception of Loghain), your character will pull out a dagger (called the Murder Knife by the fandom) and stab him/her. Even if you're playing a mage and have never even carried a dagger, you'll bring it out for the cutscene executions. Plus, it happens so fast that it often looks like you hit the victim with a rock.
Similarly, at the end of the game and if your Warden survives to slay the Archdemon, he/she pulls out a sword to deal the killing blow, despite their class. Just imagine seeing your petite elven mage doling out some BFS justice and try not to go, "Huh?" And if someone in melee gets in a dramatic slow-motion finishing move, it resets in the cutscene so the Warden can do it over.
Alter a character's armor and cutscenes - the best and/or most stirring ones included - involving that character will change their appearance accordingly. This includes if you remove their armor altogether, which players are often encouraged to do before Guest Star Party Members are Lost Forever. Cue Daveth flailing at Duncan's feet choking to death from the Taint in his underwear.
This also happens with Mhairi in Awakening.
It's also especially hard to take Alistair'sWhat the Hell, Hero? and departure seriously if you strip him down beforehand (otherwise, you will likely lose powerful, rare and valuable equipment).
Speaking of Duncan, the part during the Joining where he talks about mastering your taint is incredibly funny if you're immature.
She is also the only one that actually gets any blood on her, making it somewhat more ridiculous.
The death of Teyrn Cousland has a similar problem, where he should look like he is mortally wounded but instead looks like someone sprayed blood all over him with a hose.
The Arch-Demon's design (pictured above) can come off as rather silly, with his oversized upper teeth. Seriously, he looks like a mutant rodent.
It really would've been better if BioWare had opted for a Sexy Discretion Shot when it came to the romance scenes, instead of showing snippets of the whole thing. The One-Woman Wail, the characters still wearing their underwear, the wacky facial expressions, the fact that they're (in Leliana's case at least) doing it right in the middle of camp... All these things turn a potentially romantic or sweet scene into something either So Bad, It's Good or just completely cringeworthy.
This troper had a female human noble romancing Leliana. Not only was Morrigan standing five feet away the whole horribly-animated time with no privacy and not reacting, my Warden woke up the next morning in full Blood Dragon armor (sans helmet) with Starfang on her back. Wut.
