The movie belongs to Helen Hunt

Rating: 6/10 (26 October 1998)

Helen Hunt is brilliant in this movie. As good as Judi Dench and Helena Bonham Carter were in their Oscar-nominated roles of 1997, Hunt was every inch their equal. Her role was by far the most difficult of the film.
Nicholson basically just played himself, and did a few obsessive-compulsive tics every now and again for variety. If you're a fan of his, you've seen this before.
Greg Kinnear did an okay job, but his character was largely ignored by the screenwriters -- I never felt as though I were allowed inside his mind the way I was allowed inside the mind of Hunt's character. The only way we even know that his character is gay is because everyone keeps talking about how "gay" he is -- it's a character trait written in to annoy Nicholson's character; he could have been a saintly Jew or a saintly black man. The fact that he's a saintly gay person is largely inconsequential.
But...Hunt's performance is easily worth the price of the rental. The movie gets two stars; Helen Hunt gets four.
