don't worry, i very rarely judge shows on one or two episodes (unless those episodes were absurdly terrible, but this show seems pretty decent. I think i used to watch it every now and then when i was younger, but i didn't get any of the jokes or anything)
another option is i just record them whenever they are on adult swim, only problem is that would probably take a while because they only air like 2 episodes a night, and some nights they don't air any.
or, i could register. i never have on that site though
since i'm not an avid watcher, will the movie make sense to me? you say it explains their origins... do i need to have watched many episodes from the show to enjoy it? if not, then sure, please send me a link. i probably won't watch it tonight (gonna watch simpsons, and maybe american dad and family guy, then probably go to bed shortly after), but i might watch it tomorrow.
