Tenchi the Movie:  Tenchi Muyo in Love!
Tenchi the Movie:  Tenchi Muyo in Love! is one of the best anime movies that I have seen.  It contains:  action, sci-fi, romance, comedy, drama and tragedy, and a very good plot.  The movie is about a space criminal named KAIN who escapes from the Galaxy Police, GP, and plans out his revenge.  He first destroyes the GP headquarters and then heads into the past towards earth in order to destroy the Jurai royal family timeline since the Jurai family helped in the capture of KAIN.  In the present, Tenchi begins to disappear because of the disapperance of his mother, Achika, in the past.  So Washu sends Tenchi and the gang back to 1970 (the time of her disappearance) to protect her.  I would tell you more but I don't want to spoil the entire movie for you.
