WandaVision may have only released two episodes thus far, but it makes it painfully clear how Fuller House failed by not asking Elizabeth Olsen to play Michelle Tanner. In 2016, Netflix's spin-off sequel to Full House debuted with the whole cast from the original show — except for the youngest Tanner sister. As it turned out, Mary-Kate and Ashley Olsen, who alternately played the character in the original series and is Elizabeth's sisters, declined to return to their acting roots, explaining that they're retired from showbusiness.

This resulted in five seasons of Fuller House with no Michelle which made the show oddly incomplete. Early on, the series made an effort to ensure that she was referenced from time to time; apparently, Michelle was now based in New York running a fashion empire like the Olsen twins, and not once in the half a decade was she able to come home. Eventually, the spin-off grew so tired of finding ways to make up for her absence that they barely mentioned her anymore. In fact, the only time she was ever name-dropped in the latter season was when the character was the butt of their jokes. Fuller House didn't even try to explain why she doesn't attend DJ and Stephanie's wedding in the finale.

It wasn't as if the Fuller House executives didn't try convincing either of the Olsens to join the show, but they proved reportedly set on their decision to skip the reunion. That said, they could've reached out to Elizabeth instead, as she is also an actor, and physically resembles her sisters enough that she could pass as Michelle. If this idea didn't sound good before, seeing WandaVision proved that this should've been what was done. As she is with pretty much everything she does, Elizabeth is brilliant in the sitcom-inspired Marvel Studios series. She has great comedic timing, and if she can help recreate the feel of older sitcoms like I Love Lucy and Bewitched, it's safe to say that she would've been able to easily mimic her sisters and bring an older Michelle to life. It's worth noting that there are conflicting stories about whether or not Fuller House actually reached out to Elizabeth for the gig, but the actress maintains that they did not when she appeared on Everything Iconic with Danny Pellegrino in 2018.

That was weird, because it was also like, ‘Leave me out of this. This has nothing to do with me... and then I had to answer questions about it immediately after. I was doing press, and I was like, ‘I don’t know what anyone’s talking about. Stop talking to me about this.' I’ve heard it’s a hit. It’s very successful.”

Elizabeth did not have to be a Fuller House mainstay; Michelle could've still lived in New York running her business which would've explained why she's not in San Francisco with her family. Instead, the actress could play the part occasionally just so the character has had a physical presence in the spin-0ff. For a show that put great value in family, it's odd that she couldn't even get any time off to offer support to DJ when she was suddenly widowed or when Stephanie had Danielle via Kimmy's surrogacy. There were also no phone calls whatsoever; the least Fuller House could've done was ask Elizabeth (if the twins really didn't want to be involved) to record something for a voice cameo.

As WandaVision progresses, it will eventually tackle the '80s/'90s era of sitcom and while Full House won't be a direct inspiration for what they do for those decades, Elizabeth said that there's a reference to her sisters' old show. Regardless of what that would be, it would only further emphasize Fuller House's missed opportunity not casting Elizabeth for the role of grown-up Michelle. Perhaps if they were able to make this happen, fans of the character wouldn't feel this disappointed that she was essentially cast aside despite being an important player in the original series.
