I recently went and saw the moview This Is Forty. It goes along with the funny Knocked Up.
This movie is insanely funny from start to finish. Honestly, I laughed so hard that I felt like I did a hundred crunches by the time I left the theatre.
As a blind viewer, there were few parts that didn't have any form of verbal things going on. By this I mean there were about three music sequences where there was no talking.
Yes, some of the comedy was aimed at a visual audience, but what I didn't get to see didn't take away from the movie. It was totally hillarious. I would just recommend taking a sighted person with you to fill you in to the visual parts.
I give this movie five starts and thumbs and toes up. I recommend it for anyone with a funny bone in need of exercise. This pretty much means all adults. It isn't age appropriate for the kiddos:)
