There are two main reasons why I like Stargate SG-1 (and its spinoffs) less and less as time goes by:

1. It's a thinly disguised knockoff of Star Trek crossed with Babylon 5 -- ie. completely derivative without any new ideas of its own.

2. The self-entitled SG-1 fanboys who piss and moan that the upcoming reboot trilogy is going to ignore the SG-1 continuity (while completely disregarding the fact that SG-1 ignored everything about the original movie beyond the basic plot. Double standards much?).
