Parts of SG-1 and SG:A are okay, so those got my votes.
SGU I do not love. My favourite TV show has been turned into a rip-off of nuBSG, a show that I hate.
If Stargate could transform into the far-superior BSG, it would be a big improvement. However, the Stargate writers lack the imagination and talent to do that, or anything other than just screw up the minimally entertaining franchise that they had going. I can't stomach the mess they've come up with.
