It depends on your perspective. Some might consider it new as it brings in new elements and developments. But in a broader sense, it still builds on the existing Scott Pilgrim universe.
Definitely. 'Scott Pilgrim Takes Off' draws inspiration directly from the comic. It retains many of the key elements and storylines from the source material.
One interesting aspect could be the exploration of different relationships. For example, how the characters of Scott Pilgrim and Lisa Miller interact in ways not shown in the original. It might also delve into new storylines, like a shared adventure or a mystery they solve together. Maybe it even reimagines their personalities a bit, making them more complex or different from what we know.
Sorry, I don't have a particular recommendation. However, you could try joining Scott Pilgrim fan groups on social media platforms. Fans there might be able to point you to some really good fan fictions that feature Lisa Miller. They often share their favorite reads and might even have some that are not as well - known but are really great.
Scott Pilgrim is likely to be one of the main characters. He has been central to the previous stories. Ramona Flowers is also probably a main character as she has a major role in Scott's life.
