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: Kill Bill
Anti-Climax Boss: Beatrix's fight with Bill is the shortest fight in the entire film; lasting less than ten seconds before she kills him with the Five-Point Palm.
Budd and Bea don't even fight. He shoots her, buries her alive, and is dead before she gets back to the trailer.
Vernita dies from a single thrown knife after she tries to shoot The Bride.
Award Snub: Both films were completely ignored come Oscar season.
Better on DVD: There are so many small details that can only be caught after several viewings.
Complete Monster: Boss Matsumoto from Volume I is a brutal Yakuza boss and a pedophile. When O-Ren Ishii was around 9 years old, Matsumoto and his henchmen confronted her father (apparently, a Chinese-American soldier stationed in Okinawa), and despite him putting quite the fight, he is ultimately murdered by the mooks, while Matsumoto laughs on a couch. Then Matsumoto gets up, grabs the man's Japanese wife, tosses her on a nearby bed...and uses his own katana to stab her to death, narrowly missing child!O-Ren, who was hiding under said bed. Then, they set the place on fire and leave, laughing about it. An 11-year-old O-Ren poses as a child prostitute in order to kill him.
Crosses the Line Twice: The Crazy 88 fight. A guy gets his foot sliced off; seconds later he's seen pressing it back to the bloody stump, as if it's going to magically reattach. Another guy gets his eye snatched out (in a bit of Foreshadowing concerning where she learned this from); when The Bride is overlooking the carnage, he's still stumbling around blindly (and rumored to be a cameo by Tarantino). The uncensored fight shows the Bride taking said eye and throwing it down another man's throat.
Ensemble Darkhorse: Gogo Yubari again. It doesn't matter if she's a hypercompetent Blood Knight-ly assassin, you might as well have felt sorry for her when she was killed.
Harsher in Hindsight: Bill's line about shooting the Bride being him at his most masochistic, considering how David Carradine died.
Although she didn't get at much development as the other Vipers, Vernita is actually Not So Different than the Bride. She left the Assassin order for the same exact reasons as Beatrix. When you consider that her own daughter is around the same age as B.B., Vernita may have also been pregnant when she played her role in the Church Massacre. That may explain why the Bride got ticked when Vernita attempted to use being a mother as a reason not to be killed.
Hilarious in Hindsight: Lucy Liu aka O-Ren Ishii would later go on to provide voiceovers in Kung Fu Panda, where her character was proficient in kung fu and viper; which in China is known as a Bai-Bu-She or "Hundred-Step-Snake" (the amount of time it takes the venom to kill you), or more colloquially in the west as a "Cottonmouth."
Narm: Really just the whole movie, Notable scenes include O-ren's decapitation of a Yakuza boss, which is promptly followed by High-Pressure Blood, and O-ren's death, where the Bride chops off the top of her skull, leaving her brain exposed and unharmed.
Lots of references to really obscure movies most viewers have likely never heard of. It's not just shots though; the "My name is Buck..." line is from Tobe Hooper's Eaten Alive and it's probably not the only dialogue Tarantino lifted.
How the Bride learns that B.B is still alive. She's shocked and almost cries when BB appears all of a sudden and says "Freeze, Mommy!"
The Bride's reaction when she realizes Vernita's daughter Nikki witnessed her mother's death. She knows all too well she's trapped herself in a Cycle of Revenge.
When The Bride wakes up. She starts out as subtly confused as many coma patients are. She then checks her head to find a metal plate where the gunshot wound is. All of it is in complete silence. However when she checks her stomach to find that her baby is gone she doesn't whimper or even cry audibly despite the tears coming out. She shrieks bloody murder and silently weeps that her baby is gone. This is a Tearjerker of the Adult Fear level.
