YMMV / Piranha 3D

• Best Known for the Fanservice: Yep, you guessed it: by far the most talked-about scene is the underwater nude ballet.
• Big-Lipped Alligator Moment:
  • The nude ballet scene. The French aria, accompanied by Léo Delibes' Flower Duet, just adds to the weirdness awesome.
  • The infamous Groin Attack. Could also be seen as Narm assuming it was meant to be dramatic.
  • The ending is this. At the end of the film, Novak gets eaten by a man-sized piranha. What makes it an example of this trope is that Piranha 3DD never even mentions it, much less expands upon it.
• Billing Displacement: Richard Dreyfuss is billed first and received a Death by Cameo, although it did kick off the plot.
• Crosses the Line Twice: "They took my penis!"
• Ensemble Dark Horse:
  • In just two short scenes, Christopher Lloyd manages to upstage everybody else in the film.
  • Kelly Brook's character, Danni, is pretty much the fan favorite of the film.
  • Ving Rhames' Deputy Fallon, especially in his badass final scene.
• Fanon Discontinuity: The last 10 minutes or so (or at least the last minute) are tempting to disregard, given how well-liked characters Danni and Novak die in the final act, and how the adult piranha fall under Sequel Non-Entity.
• Fridge Brilliance: Why do the piranha continue swarming Fallon far more excessively than they do their other victims during the Spring Breaker attack? (In contrast to when there's only one available person in the water to eat, the piranha somewhat scatter into smaller swarms during the all-you-can-eat buffet that is the attack, yet they're excessively relentless in their efforts to swarm Fallon, despite his propeller usage creating an un-ignorable "Instant Death" Radius which even an unintelligent predator's basic self-preservation instincts should compel it to steer away from.) The answer to that mystery lies is that the propeller is producing an excessively large amount of blood in the water around Fallon by the second due to the dead piranha (considerably more than the individually-mutilated and scattered Spring Breakers), which is likely attracting even more piranha in a vicious cycle. Whilst the piranha work well together in swarms and are only shown attacking each-other when fighting over human scraps, Goodman did theorize earlier in the film that they probably committed cannibalism to survive underground, so it's not much of a surprise that the piranha wouldn't distinguish the smell of dead brethren's remains from the delicious smell of fresh human meat.
• Ham and Cheese:
  • Jerry O'Connell as the porn producer.
  • Christopher Lloyd isn't immune from this either, although his character feels more believable by comparison.
• Moe: Despite being a porn star, Danni inspires a lot of this feeling in the scenes where she isn't on the job, due to her Intergenerational Friendship with Jake's little sister and efforts to save Derrick from being killed, plus how her failure to do so leaves her deeply upset.
• Signature Scene: The underwater nude ballet, with the spring break massacre not far behind.
• So Bad, It's Good: A likely intentional example.
• Special Effects Failure: The gore in the 3D remake. Almost inverted; a lot of the time, it comes across as too realistic, which makes it more disturbing than Bloody Hilarious.
• Squick: Believe us when we say that no one wanted to see two piranhas fighting over a severed penis.
• They Wasted a Perfectly Good Character: Danni. Her fate doesn't add anything to the narrative besides some minor suspense, and her character feels like she could have done a bit more in the climax.
• Unintentional Period Piece: The entire film is a snapshot and parody of the Von Dutch/Ed Hardy spring break pop culture excess of the 2000s, made at the last moment in time when that culture was mainstream. Its parody of Girls Gone Wild in particular is likely to be lost on anybody born after 1995.
• Visual Effects of Awesome: Despite the above, the piranhas in the movie are completely CGI, and yet they really look believable.
