For the film:
- Nightmare Fuel: Dear God, the ending.
For the comic book:
- Tough Act to Follow: Averted. While O'Malley one-upping himself over Scott Pilgrim was going to be very difficult, the general consensus seems to be that he succeeded.
- They Wasted a Perfectly Good Plot: Considering the story's themes of accepting the consequences of one's actions and moving on, Be Careful What You Wish For, and the implication that her ex had somewhat of a dark side that never amounted to much, the protagonist being back together with him in the end comes across as slightly undermining the premise of the story.
