This reboot is very much like that of Battlestar Galactica. The premise is essentially the same, but the writers and producers have turned the characters upside down. Thus you need to go into this understanding that it will not be like the original series in many ways and you may or may not like the character changes..

That said...I have to agree that I would have thrown this new Dr Smith out of an airlock long ago just out of sheer common sense. She is evil an dangerous. In the name of entertainment she remains. Ditto the unending string of disasters and emergencies that befalls this family. The special effects are good. The family may be considered as dysfunctional by some, but do not all families have some level of dysfunction? The cast portrays the family as being hum,an with all of the faults that any typical family might have.

So, the show is fun in a campy kind of way. It lacks the polish and finesse of most of the Star Trek series. It is not always scientifically accurate. It may be even a tad annoying at times. But it is fun entertainment. I especially like the hidden and not so hidden homage to the original series, such as the character names which are a montage of those from the original series. You may find you like the show if you just don't take it too seriously :)
