Personally I feel like the show really finds it’s legs in S3 but kicks it into high gear for S6.
I’m sure every fan has a list of episodes you can skip, and while I do skip a lot of S1/2 depending on how long it’s been since I watched those particulars, personally I think they’re all important for Stargate as a whole. Necessary to watch on your second run I think, not necessarily for the first.
Luckily since I know the people I’ve watched it with pretty well, I know what can be skipped and what they’ll need to watch to really “get it”. And I summarize the episodes we skip. Sometimes I’ll even give them the option like “next episode is pretty slow, no real action but a lot of off-world things and important conversations/drama” and let them decide if they want to watch a slow episode or not.
Although honestly, how can you think the episodes where Daniel poses as Yu’s servant are boring? Sure no big explosions and action sequences, but it’s riveting.
