Did all the Trek get chased out of this topic?
I was an SW fan a lot earlier, but I met a Trekker in middle school and got caught watching reruns of TOS on the Pre-Y Scifi Channel.
Pretty much the worst part of Trek is when they do technobabble plots, which turned me off of late Voyager episodes. Also the occasional preachiness and self-righteousness that especially the TNG-era shows had. But the old movies were fun and the new reboot was harmless enough.
