I think for many performers that have seen some success, people (fans, casting agents, etc.) just want them to keep recreating their most recent, successful role. As a result, much of the work offered to them is quite similar. Not everyone can be fantastic every single time. I think some of the opinions expressed about Matthew Broderick can be said for Nathan Lane. Have we not seen him repeat similar performances in different shows? It happens!
As for "The Music Man" Matthew was hardly the reason it failed! Miscasting of many roles, uninspired directing, etc! Just not a good adaptation. (Just my opinion of course!)
