Big Hair, Soul Music, Female empowerment, showbiz cliches: abandoned starlets, drug addled ego tripping lead singers, misunderstood songwriters, race riots, pulling yourself up by your bootstraps, a secret lovechild, svengali managers and astounding performances from Jennifer Hudson and Eddie Murphy.

You want Beyonce in a big hat getting in and out of a stretch limo, or acting the glacial disco queen in a 70s disco complete with neon tubes and gay go-go dancers while trouncing anyone who gets in her way? You want a totally exciting showtune packed piece of musical fluff that entertains and blows you away?

Then this is the one for you.

I loved it.
