One thing to take into account is that movies such as Beasts of the Southern Wild, The Hurt Locker and parts of Black Swan amongst many, many others were shot on 16mm film. Now film neg has quite a large dynamic range, though some would argue not much more than an Alexa, and film certainly has a nice look about it - but these movies were shot on 'sensors' (the film neg) that were half the size of a 7D, Red, Alexa, etc. etc.
Some will argue that Red beats it because it has 5k of resolution, some would argue that Alexa beats it because of it's dynamic range and it's larger sensor, some would argue 16mm is better because it has the film look.
It's all subjective, and unless you are a DP with knowledge of camera, then it's hard to make a decision about which is 'best' - well which is best for you? Is it the Red with its high resolution? The Alexa with its film-like look and falloff? Film for its look and dynamic range? A DSLR for its price? And the best camera can change depending on the job. For example Film X might suit the look of 16mm reversal really well, whereas Film Z might suit the cleaner, perhaps more clinical, look of the Red. Film Y might suit the look of an Alexa, and then Film W might be a corporate shot for the web and so doesn't need anything better than a 7D.
And then there's all I said above about how the camera body is only one small part of a much, much bigger production. The camera itself is not what necessarily makes the film look good - that is to say a great film shot on a 7D with EF lenses will look even better shot on 35mm film with Master Primes, but an average film will still be an average film whether it was shot on an Alexa with Cooke s/5i's or a 7D. I'd rather have a good crew, a collection of lighting and grip equipment and a 5D than an Alexa with no crew, no lighting and no grip etc.
