It is disappointing to have a clip show as a season finale. Every time I watch it I think someone messed up on the budget that year and they ran out of money at the end. Oops!
But there weren't really that many clips, and when taken as a whole (with the opener for season 3) I think it's not a bad story. I always thought Hathor was an interesting character. She went about galactic domination in such a different way than any of the other goa'uld.
I will say that when I first watch thise episode I was suspicious from the start because they just travelled back in time the previous episode. Then Jack wakes up suddenly 70 years in the future. I didn't really believe they would do two time travel eps in a row so I was sure something else had to be up.
