same for me with SG-1 and Atlantis. I've also watched SGU a couple times. I really liked where they were going with that show and wish it would have continued. I check every once in a while for news of new series or movies. Sometimes I'll see things that sound interesting and then for some reason it never happens. Recently there is this: https://www.gateworld.net/news/2022/07/fourth-stargate-series-would-introduce-unique-gate/ I'd watch it!
edit: not as recent as I thought, that was last July... but still would be interesting
SG-1 wasn't on any streaming services I have in the UK for ages but just noticed off the back of this that it's back on Prime. I haven't watched it for SO many years. Great show.
Halt and Catch Fire I've seen 2-3 times and I love it.
