Brilliant, Just Brilliant! (Major Spoilers)

I was so stunned by this film. I don't know why I passed it by so many times in the video store without picking it up. This film also helped two great actress's get their career in film off to a phenomenal start. This was Glenn Close's first feature film, and it was Amanda Plumnmers third. The acting in this film was also exellent. Glenn Close gave a terrific performance. Robin Williams was also great. But the side characters really helped make this movie wonderful, John Lithgow, Mary Beth Hurt, and Swoosie Kurtz were great! The only thing I did not really understand was the whole thing with Pooh, what was her motive for shooting (possibly killing) Garp? The only thing I can come up with was that she was jealous of his relationship with her sister Cushie, but that seemed to simple to me. I never read the novel so if someone could shed light on that I would appreciate it.
