I was fine with the mother dying. It was just the immediate twist of "Mom's dead, and this is me now spending 9 years explaining to you why I want to go bang your aunt".

I think the bittersweet ending of finding out that the mother was dead all along and Ted was telling the story to his kids would have been a great ending without the add-on Robin double-twist.

That would have been better

I'm guessing you realised you hated it after only a few episodes and it only got worse as you watched the rest 😏
