I watched the first five episodes of Lost in Space.
While I found the first two episodes pretty engaging, by the third I started getting tired with the proceedings; most of the characters are boring and there seems to be more padding than story going around. Also, what I've read about Dr. Smith's character evolution doesn't sound at all appealing to me.
Suffice it to say, I like the premise of the show, but the execution doesn't inspire me to carry through with the rest of it.
