House creator David Shore recently debunked the popular theory that Wilson was hallucinating House in the final minutes of Everybody Dies, yet that theory never really made sense and didnt even need to be debunked. Houses first episode is turning 20 years old, but some fan theories and debates about the show feel as relevant today as they were two decades ago. House has a complicated legacy, with some seasons being much better than others. One of the most controversial aspects of the show was its ending, with Houses series finale still being a topic of debate 12 years later.
