10 TV Shows Utterly Ruined By Their Final Revelations

9. St. Elsewhere - It Was All An Autistic Kid's Dream

If you thought HIMYM's shock-for-the-sake-of-it ending was bad, the finale to medical drama St. Elsewhere made it look positively well thought-out and reasonable by comparison.

The final episode reveals that the entire show - that's six seasons and 137 episodes - was actually imagined by an autistic boy named Tommy Westphall (Chad Allen), who has a snow globe containing a replica of the St. Eligius hospital.

The shock reveal left fans both confused and incredibly upset, knowing that six years of loyal viewership was basically thrown away with an ending just north of "it was all a dream."

It's basically the blueprint for how not to end a TV show, though to its mild credit, it's still being discussed 30 years later even by those who've never seen the show, and even prompted a popular fan theory that countless other TV shows also exist within the "Tommy Westphall Universe."
