Hot take: S2 is only even remotely considered "good",because of the online engagement and fun had theorizing "Earth X".
Referring to how when episode 3 dropped,the Internet was BOOMING about the show. Pointing out all the weird caveats of the other universe. And how all caveats lead to "Earth X".
If you completely disregard that phenomenon,and/or rewatch S2, it's such a mediocre season. Meaning the best part of the season,wasn't even the content in the season itself in a literal sense,but the engagement that was had when Episode 3 aired.
Unfortunately,the reveal of "Earth X" didn't remotely do anything for the plot other than "omg they're all racist! And there's only white people". We don't get a pay off with anything,due to how the season wraps up. We also don't spend much time in this universe. Another episode would've greatly helped the world building. There's a lot of talk and no show. This is partly due to this show only having 8 episode seasons.
Anyways,I miss Peacemaker. And It sucks we aren't gonna see Chris's fate anytime soon. By now ,if it was a regular ongoing streaming show,we would've gotten word of Season 3. Possible start or end of filming announcements,behind the scenes pics,etc. but sadly there isn't going to be a S3 .
