Broadly speaking I agree with the Harrap above - I never liked Phantom Menace much and that continues to this day, but I enjoyed both Clones and Sith and consider them worthy additions to the franchise, although both are not without their faults :)

As far as Indy goes, for me the first will always be way out in first place, with Temple being a distant second (yes I know its the least 'Indy' of the series, but I really liked it) and the other two yet further down the chain (I have never been especially fond of Last Crusade)
