Could have been 10 minutes shorter ... but other than that, OK.

And I say that as an old fart who has never particularly liked Christine Aguilera, or her image or brand of pop (am I getting old?).
It's not 'Funny Girl' or 'Cabaret', but it's a bit of a mixture of both, with some nice moments for the supporting cast - especially Stanley Tucci, who once again gets to play "the gay" in that interesting, undemonstrative style of his - and not much needed from the leads, who do their jobs as required.
And if that sounds like a put-down, it's not meant to be. I enjoyed watching the film - it's just not up there with the ones I mentioned. And the business of it being too "Bob Fosse"-esque? Pah. If you're going to mimic, at least pick the best.
My preference would have been for a few more classic lip-synced blues tracks; but at the end of the day, it's a nice story, well told. And it reminded me that, even with all that prodigious female talent on display: It ain't what you got; it's how you use it.
