As the for the humor thing I have to disagree whole heartedly, Crichton always came off as having gone mildly insane to me and I didn't find any of his references even mildly ammusing, infact in the shows entire lifetime I don't think I laughed once.
SG-1 was never meant to be all that funny, it has a lot of moral issues (which I love) a lot of character and an entire universe out there interacting with its self even when the team don't see it. Now Jack is obviously smarter than he lets on, I've always seen his humor as a defence mechanism to stop anyone getting too close after charlies death, the humour is (for better or worse) pretty much like mine, they have the odd humurous episode (eg the 100th episode, wormholeXtreme) but for the most part they let the impact of the episodes stay by keeping the situations real but allowing the characters to be quirky and humurous. No one could ever accuse Farscape of believability.

I do agree that the increase in space travel is a let down, I always find the episodes centred around this are of a lower quality. Most commonly it is used for the two parters, but I thought the prometheus was a real exception in this case, the parts were stolen and reverse engineered from the crashed mothership and I'll be honest the fact that it was human in design and looked it (atleast from the inside) kept the feeling of modern day earth venturing out. I especially liked the episode where they accidentally detonated an EMP above a nearby planet and had to convince the locals that they weren't under attack, it had all the feel of a classic SG-1 episode but with the new twist that they had to prove they weren't a threat, even with that gigantic ship.
The production of the prometheus didn't go off without a hitch, a G'oald had to be manipulated into finishing the engines, and even then the hyper drive didn't work as expected, a real fumbling attemtp by earth to use technology over their heads out of a NECCESSITY. The show opened up the fact we were experementing with alien technology early on with the 2 gliders fused together (also a complete disaster). No maybe the time period is a little too condensed, maybe not, if you knew a hostile alien race was coming how much of your resources would you focus on defending against that race?
Not seen breakdown, seen Soldier, Escape From fils etc.
