Plot
Two seemingly dumb teenagers, Bill S. Preston, Esq. and Ted "Theodore" Logan, set off on a quest to prepare the ultimate historical presentation with the help of a time machine.

Why It Rocks

 * 1) The idea about two teens traveling to the past in a time machine made by their future selves is very interesting.
 * 2) Great acting, from Keanu Reeves, Alex Winter, and George Carlin.
 * 3) Decent special effects.
 * 4) Likable characters, such as the afromentioned Bill and Ted, and their mentor Rufus.
 * 5) Funny moments such as Beethoven playing rock music on a keyboard while Joan of Arc exercise dances with a group of people and the 69 joke.
 * 6) Good grasp of the source material, with many historical figures acting like themselves.
 * 7) Alongside Back to the Future it popularized the time-travelling genre, which has become highly overused in media a lot.
 * 8) The soundtrack is AWESOME, especially the heavy metal ones.
 * 9) Funny lines, with the best part being from Abe Lincoln himself: “LET’S PARTY ON, DUDES!”

Bad Qualities

 * 1) Some of the jokes can be tasteless or unfunny.
 * 2) The effects may have not aged well, even for 80's standards.
 * 3) Plot hole: How did Bill managed to quickly remove his armor if the other knights were chasing him for like, five seconds?
 * 4) It can be inappropriate at times even for a PG rating.
