Much like Judd Apatow's preceding film 'The 40 Year Old Virgin', this
takes a silly high concept Hollywood idea (slacker slob impregnates
upper class hottie, in spite of all odds they have the baby and fall in
love), injects it with sharp humor, highbrow and low, pathos, good
acting, and even some real insight into people and relationships.
Seth Rogan is terrific, but so is Catherine Heigel, Paul Rudd, and
everyone in the supporting roles.
Not a huge visual upgrade between the Blu-ray and the regular
DVD, so if cost is a factor...
