this is a pure old man circlejerk fantasy

I can't believe this movie got 7.8 on imdb. it's nothing but a pure old man fantasy. he is this kooky weird dude. everyone loves him though. he's the center of attention everywhere he goes. the dialogue is corny and boring as hell. he even cheats on his gf in new zealand and gets laid with a random old woman too. wtf? come on. I went into this thinking it was gonna be really cool about how he built his bike but it has virtually nothing to do with that. The geriatric genre is big now because the population is getting older.
