Rehabilitation is big business in the United States, and remarkably monolithic.
28 Days gives a reasonably accurate impression of life in a typical private rehabilitation facility and of some of its highs and lows. But, although you may feel uplifted by some of your fellow sufferers, the film also shows how others can depress you, offer you dope, or involve you in damaging relationships when you're feeling lonely and vulnerable. Eclectic it isn't, and no other approach gets a look in. The film suggests that US rehabilitation involves lots of hugs, tears, group chants, and saccharine effusions of Panglossian optimism. This is not everyone's cup of tea.
