Well, a 'flicker novel' can be thought of as a creative type of novel. It may use short, sharp descriptions or events that seem to 'flicker' by as you read. It could be compared to a montage in film, where different elements are quickly presented one after another to build an overall impression or story. For example, the plot might jump from one significant moment to another without much in - between filler, making it a very dynamic reading experience.
It's a bit of both. 'Goon' has roots in real events, but the filmmakers likely took some liberties and fictionalized certain aspects to create a more compelling narrative for the audience.
Definitely not. Goon 2 is a made-up story. The characters and plotlines are invented to provide an engaging and enjoyable viewing experience rather than being rooted in reality.
