>Yes and no. The traditional format is indeed five-seven-five, but in recent years, the format's boundaries have been expanded a little, especially in English haiku, so that even two-line haikus are acceptable. According to those more liberal groups, it's more important that the poems serve as meditations on nature than that the format be strictly followed.

Hmm, so technically, haikus about movies aren't really haikus at all? I'm relieved.
