A bit difficult to compare like for like. The original first three Star Wars films were a brilliant example of a traditional story arc, using the same format as Greek, Roman and modern literature the heroes quest just hooks you in young or old. Lucas in many ways has never bettered them and for what they are, they are damn near faultless. Star Trek has a great history of posing interesting philosophical questions and this reached it's apex under te captaincy of Jean Luc Picard. Shatner was fun and for baby boomers and those that enjoyed it first time around will probably never be beat. I loved generations when I used to do buckets and other mind altering naughtiness, the combination was great fun. Can't choose between either, feel nerdy enough already discussing it. Must wash brain.
