MASH may have occasionally teased out a romance between Hawkeye and Margaret "Hot Lips" Houlihan, but that would have been a big mistake. MASH is one of the biggest TV shows of its era and broke a few rules along the way. The death of Henry Blake on MASH was a major event, as it was almost unheard of for a network sitcom to kill such an important recurring character. MASH became more of a dramedy as it evolved too, and rejected the notion its characters couldn't evolve out of static arcs, like other comedy shows of the time.
