One of the trademarks of “How I Met Your Mother” during its nine-season run was the way it whooshed forward and backward in time. But during the clever — and controversial — series finale Monday night, the jumps were usually forward, pulling us into the 2020s and the futures of best friends Ted, Robin, Barney, Lily, and Marshall. Rather than going for poetic or ambiguous farewell gestures, the writers opted to be quite specific about each of the characters’ fates.
No, the hour wasn’t a gonzo trip ahead through the deaths of each character — only “Six Feet Under” could pull that one off. But at last we reached the point where older Ted has finished telling his two kids how he met their mother, while they’ve been sitting listening impatiently for-seemingly-ever. The show came full circle, in a way — and then it moved just one more very significant step further (beware: spoilers).
