It's far from perfect but 'Legal Eagles' is quite nostalgic and entertaining. The story is very contrived especially with so many plot holes and the characters aren't fully fleshed out either but it has a very noire style approach and does keep you in suspense. The humour also works quite well. On the technical side it's a decently made film, nothing too flashy which is good. I also liked the presentation of the art world.
No matter what one says about 'Legal Eagles', for me the highlight is easily Robert Redford and a very cute Debra Winger. Both actors are spellbinding, delivering subtle and charming performances. As performers, they just look so comfortable with each other. Their chemistry is amazing and their scenes, especially their on-screen banter, are a delight to watch.
Daryl Hannah's role is sketchy but she looks sizzling and I enjoyed her sequences with Redford and the scene where she demonstrates her art. Brian Dennehy is wasted. Terence Stamp is adequate.
So yes, it's got its flaws but how can you not enjoy it for Redford and Winger?
