For a less demanding pregnancy story, one could try Juno. The fimla has already been recommended in the countdown to the Oscars. Juno was last year's sleeper hit.
The independent film, about a smart, cocky and heart-wrenchingly vulnerable teenager who gets pregnant, is written with wit and sparkle.
Not surprisingly, Juno's writer Diablo Cody, who was, incredibly enough, once a stripper, walked away with the writing Oscar.
Juno has heart and a great affection for its wonderfully dysfunctional characters. Watch it.
