The finale of "How I Met Your Mother" left me utterly disappointed after nine seasons. The elaborate buildup to Barney and Robin's wedding, only for them to split up in the penultimate episode, felt like a waste of time. Barney's regression to his old habits was particularly frustrating after the transformation he underwent for Robin. Similarly, Ted's narrative about meeting his future wife only to have her die in the end lacked emotional payoff, with the kids' indifferent reaction highlighting the disconnect. Despite seasons of showing Ted and Robin's incompatibility, the series inexplicably circles back to them in the finale, overlooking the fundamental differences in their personalities. The rushed introduction and demise of Ted's supposed true love in the final season failed to evoke the intended emotional response, contrasting sharply with the impact of other plotlines. While Barney and Robin's storyline was compelling, the abrupt breakup undermined the investment in their characters. Despite these flaws, Lily and Marshall's arc remained a highlight, providing a consistent and heartwarming narrative thread throughout the series. Ultimately, the disjointed ending and unresolved plotlines detracted from the show's overall impact, leaving fans with a sense of missed potential.
