There is one great improvement needed to the navigability of this website. Say I am interested in the rankings or reviews of user mpowell (either because I like his views or because I am a friend of his). I hear about a particular movie, and I wonder what mpowell's view of the film was, so I want to check it out on Criticker. It seems to me that as things stand there is no easy way of doing so.
I would like to propose two changes that I believe would remedy this problem. First, when I go to a user's profile page, there should be a box where I can enter a movie title (similarly to the way I search for a movie to add to a collection), and bring up that particular user's ranking and review for the film. Second, when I go to a film page, there should be a box where I can enter a username, and, again, bring up that user's ranking and review of that page's film.
By having both these options, it will be possible to cover two situations: (1) I go to a user's page and can look up his/her review of Film A, then Film B, then Film C, and so on; and (2) I go to a film page, and can look up the reviews by User A, User B, User C and so on.
I believe these changes would greatly improve the sense that when I visit the Criticker website, I can readily obtain the specific piece of information I am interested in reading.
