the ones I've seen have been largely derivative and unwatchable, usually with very poor voice work. however, once somebody gets a sizeable staff (e.g. 120 workers) and a big render farm, I think some good work will be possible. if they want a realistic deadline (their brand-new hardware and software will be obsolete in 9 months), then they need to keep it down to 10 minutes per frame for each 5-minute segment of a 90-minute film. with 20 teams in parallel, that should allow them to get it done in 6 months, having produced and edited about 240 minutes of footage, most of which will be unuseable. it will be mind-numbingly confusing and chaotic in the extreme, but there are many folks here who are capable of directing and producing such an effort.
