I tried the pilot of Resident Alien and, while I simply love the lead guy from Firefly in it, some his behavior and that of other characters grates on me in ways that I cannot even explain. Real people simply don't behave like this, lol. Not sure if I can stomach another episode, tbh. BTW, had he actually executed that screaming child, I might have stuck around for at least one more shot!
The show is about an extraterrestrial taking the identity of a man in Colorado, and you're bothered that the people aren't behaving realistically enough?
