Didn't AOTC perform rather poorly in relation to TPM, certainly in financial terms? And if I was going to make money I wouldn't do it with a film like ROTS (although certainly in terms of not letting my son watch it until he reached a certain age it actually made him want to watch it more and now it's his favourite of the series!). I don't deny TPM is the most juvenile of all the films (although that flabby middle bit on Coruscant is a real turn off for kids) and certainly the interview quoted above speaks for itself but when I watch the prequels it never occurs to me that the governing factor is mammon.
