The main beef I have with Criticker's interface is that I don't understand the difference between the wish list and the built-in Remembered Films collection. I think that the Wish List should operate more like a regular collection.
For instance, you can search from your Remembered Films and export the collection, but you can't from the Wish List. Also when I do a search on a film and click to see the details before I rank it, I can see "Add to my wishlist", but there is no "Remember" or "Save to Remembered Films" link there. The only way I even found out about Remembered Films was when I was looking at the "Other Recommendations" in Explore > Recommendations, where there is a tiny "remember" link under the movie images.
In summary, I'd like to see more "Remembers" sprinkled around, and also make the Wish List a built-in collection so it can be searched and exported.
