While I love Trek I believe Star Wars wins this contest hands down. For my generation these movies were life changing. They may have lost some magic over the years due to a loss of innocence (and three crappy prequels) buts their importance in movie history cant be ignored.
wow this is like picking between children haha even though i dont have any if i HAD to choose i guess i'd go with SW just by a bit, but I love ST to death as well
