I know this is gonna be an unpopular opinion, but...
I really disliked the film version of HAIRSPRAY. It seemed flat and colourless compared to the Broadway production, almost as though it was trying to be a shot-for-shot recreation of Waters' film with a few songs thrown in.
I had the same problem with MAMMA MIA, which I enjoyed enormously seeing on stage. It's almost like, when they made films of these things, they had to make them so very literal ("We have to! It's a movie, not a play!") that they miss the core element of fun that makes these shows so enjoyable. Believe it or not, Travolta was, for me anyway, about the only saving grace of the film: he was clearly having a blast, while everyone else was so very obsessed with "acting".
And I fear that ROA will get the same "literalist" treatment and, as a result, just bog itself down. Who knows, maybe, with luck, they'll come up with a script that makes the leap from stage to screen as successfully as CHICAGO did... but I'm not holding my breath.
