Yes, there are some far-fetched plots such as the whole thing with the robot telling Will to "trust" him which somehow meant I am going to disintegrate and become part of your heart, then SAR will stab you again and I will then take over his body so I can come back in my original robot form. But, the family values, cute banter between the family members (which Judy says includes Don), great special effects and creative ideas more than make up for the shows fault. Many of the plot twists are handled quite well so don't fret over a couple that aren't as good as they could be.
I was emotional during several episodes partly because some of the family scenes are so sweet, partly because of the amazing special effects and partly because I just wished there was more wholesome entertaining sci-fi like this. You may find a few details that don't add up or aren't explained well (especially how Dr. Smith escaped death in last season's finale), but try to find better sci-fi shows out there and you'll find there are little to none.
