It's entirely possible that sending the audience out feeling lousy was intentional

Great movie! If you want to be entertained and have a few good laughs, see this movie. The music is also very good,

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?
