While it mostly works on the back of Stewart's presence and Hull's looney performance, Harvey suffers from an extended focus on relatively uninteresting side-characters at the expense of Stewart's Dowd. The central premise works, but the film spends way too much time having Dowd explain the already simple central conceit to other characters, resulting in long dead-patches. Additionally, the script gets bogged down in contrivances that come off as though they were written with an end point in mind and, as a result, the progression doesn't feel natural. If the game of escalating misunderstandings is done well, it appears effortless and Harvey often feels labored in its attempt to move pieces from point A to point B. It's sweet and charming, but this is a minor work. Its status as a classic doesn't seem to hold up under further scrutiny.
