i read all the comments about season 2 not being good. although it might not be as good as season 1 it’s not bad at all? yes they could’ve done some things differently but still very much enjoyable!!
if you're planning on watching this. please note that it's a slow burn. it feels like the beginning doesn't really go anywhere, but it'll get much after ep6. that's when things actually start to make sense (to me at least). the first few episodes definitely feel like "fillers".

the only thing i wished for was a little more screen time at the end where they’re back the in present
