Like Father Like Son vs. Vice Versa - Brain Transference vs. Transmogrification

Here’s a disturbingly well thought out theory on the role reversal between Fred Savage and Judge Reinhold in Vice Versa compared to Like Father Like Son, another film in the sub-genre. That this could even be considered a sub-genre is even more disturbing.

From IMDb:

One of five body-swap movies all released around the same time. The others were 18 Again! (1988), Like Father Like Son (1987), Big (1988), and Dream a Little Dream (1989).
