the second is just as over the top as the first IMO. just the premise of the first film, 80s surfer dudes going through time collecting famous historical figures for a school final, it is incredible. could you ask for such an amazing, silly concept? Beethoven playing a bunch of synths in a Radio Shack. Gengis Khan decking himself out with sports gear and trashing a mall. Napoleon experiencing a modern water park. the scenarios almost write themselves. they nailed them in such a classic way.
the second film does that one more. now they get into a more spiritual realm, they explore the mystical consequences of such dimension altering technology that they have been privy too (the phone booth). they have tech/identity crisis, faced with their Evil Robot versions, who disrupt a school in the future where George Carlin brings in the guitarist from Faith No More to teach a VR class. from there the film careens into madness, with the duo dying and experiencing a purgatory as ghosts on earth, they take over the bodies of two police officers about to address a roomful of policemen (this scene is beyond funny) then crash the party at a New Age seance, whose frightened yuppies end up banishing them to the afterlife. this sequence is brilliant, they do an extended riff of Ingmar Bergman's
The Seventh Seal, by not just playing chess against Death but also Battleship and Twister. they go to Hell where they thrown horns at Satan and they go to Heaven where they quote "Every Rose Has It's Thorn" by Poison to God. the movie ends with a OTT showdown of time travel deus ex machinas as our duo defeats the time warriors and instantly go into an incredible concert broadcast around the world of "God Gave Rock n Roll to You" plays by Kiss. this leads into a montage detailing the triumphant pop culture rise of Wyld Stalyns, at one point it says they are playing a concert on the moon. it really is one of the great all-time film endings. i am glad to see them working together again and can't wait!
