In the movie Homer messes up big time to the point where he almost destroys Springfield, the town wants him dead, Bart finds a new father figure, and Marge tapes over their wedding video. In the end, he saves the day, Bart and Homer finally bond, Homer learns that other people are more important than him, a minor character is Killed Off for Real, and Lisa meets her first real boyfriend so far. Unlike other future episodes, Holiday of Future Passed isn't told by a fortune teller or a look into the future. The main plot is set up by Bart and Lisa whining about having to get their Christmas pictures taken, then fast forward. Unlike other flashfowards, this one seems to be canon.
