There are a few funny moments in The Proposal. How could there not be with Ryan Reynolds and Sandra Bullock? But there's no reason at all for the two characters to fall in love, except proximity and the fact that they're both nice-looking.
I'll say the same thing about Jersey Girl, which is not the recent Jersey Girl with Liv Tyler and Ben Affleck but an early '90s rom-com with Dylan McDermott and a girl that I recognize but can't name. It's all so unbelievable. Or maybe any girl can force the guy of her dreams to fall in love with her by getting into a car accident with him and then relentlessly and annoyingly pursuing him. Hey, I love Hulu, but their movie selection is limited.
