Krem should have just kicked Krypto
This is by no means my only issue with the movie but it would solve a major issue I had with it.
Krem is supposed to be this sick bastard that kills Ruthye's whole family in cold blood. But when Krypto attacks him, he shoots him with a poison dart that conveniently keeps Krypto alive for the rest of the movie and also imposes a 72 hour countdown on the plot. But instead of creating a sense of urgency, it feels like the movie is telling them to wrap it up.
But the worst part is that Krem carries the antidote around his neck. ??? Who does this? Why would he do this? This was such a lazy choice.
Krem should have punted Krypto. Callously abusing and injuring a beloved animal would have felt more shocking and evil. It still would have motivated Kara to help Ruthye hunt him down, but it also would have given the story much more time to spend developing their relationship and their journey. They could explore more planets or overcome more challenges together. And more importantly, Krem wouldn't need to be wearing an antidote to wrap up that plot point. They can just check back on Krypto at the end after they beat The Bad Guy. Maybe it's been a week or a month. But he's recovering and he's happy to see her.
It would have given the movie a lot more breathing room and felt less contrived.
