YMMV: Casshern Sins
- Adaptation Displacement: This series is much better known in the U.S. and many Western countries rather than the 1970s anime it's rebooting, largely due to the fact that it was a centerpiece premiere in the US revival of the Toonami block.
- Anti-Climax Boss: After Casshern loses to Dio in the penultimate episode, you'd expect a climactic battle in the finale, but no, Braiking Boss simply dies on his own instead of being taken out by Casshern.
- Broken Base: While the visuals and soundtrack are lauded by most people, reception to the execution of the plot (its method of storytelling, its pacing, etc) is mixed. Some people find it an amazing Jigsaw Puzzle Plot, others find that the series was disappointing in spite of its great potential and compelling themes, feeling that didn't really go anywhere, wasted too much time to get to the actual plot, and overall had an unsatisfying conclusion with way too many loose ends.
- Crowning Music of Awesome: The majority of the soundtrack, which was composed by Kaoru Wada of Inuyasha and Princess Tutu fame.
- Cry for the Devil: Both Dio and Leda get a lot of sympathy from both protagonists and probably audience by the end.
- Everyone Is Jesus in Purgatory:
- Braiking Boss and Casshern come across as The Atoner versions of Satan and The Antichrist respectively.
- It's difficult to ignore the Messianic characteristics of Luna and her subsequent resurrection makes her very Christ-like…if whether she's helping the world or not weren't completely debatable.
- The obsession of the robots with killing Casshern and eating his flesh, convinced that doing so will make them immortal sounds like a twisted version of the Eucharist. Likewise, the fact that drinking Luna's blood grants eternal life invokes Eucharistic imagery.
- Evil Is Cool: Braiking Boss hits the mark and runs with it.
- Foe Yay: Dio and Casshern, so much. Given the show's propensity for hidden meanings and double entendres, it's probably intentional.
Dio : "If there is a meaning to life, then you are the meaning to mine, Casshern!"
- Jerkass Woobie: Luna can seem pretty heartless when Casshern finally meets her, but it becomes a little more understandable when it's revealed that she was forced into the role of a robot Jack Kevorkian because of her powers, and couldn't handle the psychological burden that put on her.
- Like You Would Really Do It: Did you think Casshern was dead at the end of Episode 21?
- Memetic Mutation: People like keeping track of the number of times Casshern's name is said per episode.
- Suspiciously Similar Song: The theme song of Jin, a oneshot robot who sided with humans, sounds an awful lot like the theme from Terminator 2.
- Uncanny Valley: Subtly employed in the designs of the more humanoid robots. When paired with the rare glimpses we get of humans, it becomes apparent just how eerie the likes of Casshern or Lyuze look with their stylized facial structures and perfect features.
- Wangst: He has reasons to lament, but Emo Casshern might grate your nerves at times.
