1. If you want mindless techno-babble, then this show isn't for you. 2. If you don't manage to appreciate what good... no, let me rephrase that for you: exquisite acting is, then you definitely shouldn't watch it. 3. If you expect to have a crew of four, including a science doctor, an alien, a military and some random Indiana Jones guy, all of them solving new let's-save-the-Earth-before-lunch problems, then skip BSG, is not for you. 4. If you're afraid of seeing real human stories put into a SF shell, perhaps you should go back to Star Trek (and I'm a trekkie too, but...) 5. If you crave to hear 'shields up' or 'engage' or other classic one- liners, then you should rather settle for "frak". Or is it "frakk"? 6. If you're unable to follow a 4 season-long story arc with every episode adding something precious to it without having withdrawal symptoms, then you should really don't give it a try. 7. If all that you want is see people in tight suits flashing laser pistols and teleporting from harms' way, then change the channel. 8. If your interest for spiritual quests, tough sexy girls and people really dying and not returning is something like zero. Oh well, you might skip that 'dying and not returning part' :P 9. If you don't like space battles rendered so real (and with as most care for real physics as a TV SF show can take) that you feel you ARE there. 10. Finally, if you have a mind so closed that you cannot appreciate what the best SF show ever made is all about.
In my opinion, any problem that somebody would have with this show would be his/her problem, not the shows. For the rest of us, BSG raised the bar so high, we almost cannot enjoy other SF shows anymore.
But then... we can always re-watch it, and hope others will learn from it, too.
