There were some people who just stopped working on their tracks after they had it "finished" even though there may have been room for improvement. Perhaps some of these may be the ones you would point fingers at. Not sure which ones you're talking about, compared to who ended up stopping their progress on tracks.
The Tales project certainly shoots other OCR remix projects out of the water (such as VotL and CS), because there was some sort of quality control, and people were kicked for sucking.
I agree that the project doesn't really sound like one cohesive project because of all the styles (disco, trance, omfg guitarrrrzzzzz, orchestral, etc), but had they tried to go with just one style, then the project would have only appealed to a few people who like the chosen style. With the various styles, it allows more people to enjoy the project (in full or part) as well as introduces some people to styles they may not normally enjoy. So, I think the various styles are more of a positive factor than a negative one.
I just took a whiff...he is.
