Flesh and Bone
I think Gwyneth is a great actress. Some of the lesser known films where she's shined are Flesh and Bone and Deadly Relations. I'm sure she's great in Hard Eight also. While some of her well-known movie characters are bitchy or shallow, the unknown roles of gritty, grifter-like people allow her to showcase her solid acting skills.
Note: This forum should refer to movies she's appeared in and her acting, not her lifestyle site or commentary on perceptions of her "alternate reality" viewpoints.
