A portmanteau of "prequel" and "reboot", a preboot is a film in a series that takes place before its predecessor(s), but also tries to rewrite the history of the series as well.
X-Men: First Class is widely considered one of the best preboots in modern cinematic history. It's an origin-of-the-X-Men story that fixes the flaws found in previous X-Men movies.
