How I Met Your Mother
We've been patient for five long seasons, but it may be time to meet the mother. There have been so many filler episodes that it seems like all the original characters are in a rut: Lily and Marshall are the dull marrieds, single Ted is just getting more frustrating, and Barney and Robin's relationship was just fast-forwarded through.
My suggestion: Amp up the drama in the existing relationships, or bring back something as silly as Robin Sparkles. I can wait a little while longer for Ted's future wife if our young New Yorkers get a bit more substance to work with. Oh, and stop with the celebrity guests! Unless she's you-know-who.
