If anything, How I Met Your Mother suffers more from having too deliberate a premise than any sort of flaw or decline in quality over the years (though it's had its off seasons). It's become something of an ongoing joke that Ted's poor kids have been listening to their dad regale them with an incredibly lengthy account of the years he spent scouring the Manhattan dating scene for the woman destined to become his wife and their mother. (Because what kid doesn’t want to spend who-knows-how-long hearing about all the failed relationships their father had before settling on their mom?)
But, to its credit, How I Met Your Mother delivered on said premise in such a way that even the most casual of viewers will likely be interested in knowing just how Ted met his kids' mother. So, even though the longer the show went on the more preposterous the idea that two kids were still listening to Bob Saget's narration became, there was always the notion that one day it would all pay off. While the series experienced the inevitable dearth of fresh ideas and truly witty comedy, the penultimate season ended with our first glimpse of Ted's future bride, making us forget about all those year's of wheel spinning.
