If these two tv series had a love child, it would be Wandavision. I'm only two episodes in and holding out hope that the story improves dramatically but thus far it's not been good.

If you aren't familiar with Bewitched, this is a sitcom from the early 60s that starred a witch (Samantha) and her ordinary husband (Darren). Shenanigans ensue. The style also resembles the Dick vanDyke show. Wandavision nails it but sitcoms have evolved so much in the past 60 years, it feels dull.

Life on Mars, on the other hand, is more recent and there's a version in the US and UK. That story follows Sam, a detective from the 2000s, who is hit by a car and falls into a coma only to wake in the 1970s. In the 70s, he works as a detective but there's no modern forensics, suspects are beaten, no cell phones, no modern interrogation techniques. The similarity here is that occasionally Sam hears voices from his real life (such as through the radio or TV). Is it all Sam's imagination? Did he actually travel back in time? Will Sam wake from the coma? The show leaves the audience to wonder giving just the occasional clues.

Life on Mars is a great show and a trope that is usually successful (such as with 12 Monkeys). However, in Wandavision, it's sorta ruined by the dorky 60's sitcom setting. Unlike Pleasantville, another similar example of this, it's done in a very campy and unfunny way.

I certainly hope it improves but unless there's significant character development in the rest of the cast, this show is not going to be very successful.
