Yeah, I don't know the Echo character at all from the comics and forgot she was going to be on the show, so when we saw her at the end of episode 2 I thought she might be some Yakuza chic who wanted revenge against Ronin for killing her father lol...
Darkseid had so much potential and ended up looking pretty cool, but IMO he was undermined by several questionable decisions by ZS. First the release of those early, unfinished CGI pics of him on social media that made him look anything but menacing, then starting the movie with him LOSING a battle on Earth. And then having him forget where his precious anti-life equation was located, so he kept conquering worlds trying to locate it again (for 5,000 years!) like some senior citizen wandering the mall parking lot trying to find his car. No, Thanos wins this one hands down.
