I saw Amélie a couple of weeks before it's closing date on Broadway and was able to get front row center rush tickets. The thing that stuck me was while wasn't unpleasant, it wasn't really about anything. It didn't feel like the people who created the musical version had something to say, they had just decided they wanted to make an Amélie musical, had the plot from the movie as a framework, but it had no personality of it's own.
Later that same day I saw Indecent, a play stuffed with facts and ideas it felt like playwright Paula Vogel needed to get across, and while granted it's trying to be a very different type of theatrical experience, that contrast in purpose really made it clear for me how much passion was missing from Amélie.
(BTW, the juxtaposition of that double header might be the closest anyone gets to seeing Katrina Lenk star as Amélie.)
