How I Met Your Mother vs. Definitely,Maybe

Today being Valentine's Day, the romantic comedy Definitely, Maybe opens in theaters. Given what I have read of the film, I'm surprised I have not found many comparisons to CBS's sitcom How I Met Your Mother (a show I find to be unevenly paced and sometimes not funny enough, but is decidedly clever and better than almost any other sitcom in the last few years). The conceit sounds suspiciously similar.

Granted, I have not seen the film, so making a judgement call based on the conceit is like comparing Cloverfield to The Blair With Project. The premise, content, result and even the tone are absolutely distinct in this case, so I wouldn't be surprised if the same was to be said about the HIMYM and DM.

Nothing against Rachel Weisz or Isla Fisher, but my vote goes to Elizabeth Banks.
