Although i agree that much of the Farscape puppetry work is of a higher quality (on the small screen) then what came out in much of the PT, the problem though is that the puppetry has a higher level of difficulty when filming. George, it's been written, is continually evolving the look and storyline itself, puppetry wouldn't allow for him to change things later on, easily. Puppetry is against his prefered method of movie making. What would you all have converted from digital to puppet? Jar-Jar...the Kaminoians...Dexster. (Jar Jar's manerisms would have been greatly reduced, the Kaminoians wouldn't have been able to stand up or walk, but Dexster at least for the close ups at the table would have benefitted greatly) Although i love the Farscape work, and would guess that they could have done it at the HD quality George was up to, to do it in the time allotted would have been very difficult. After 28 years they still couldn't get a working R2 to do what was needed, you think George had the patience for more mechanical contrivances on set... Puppetry on set would either have added a year of production (overall) or reduced the number of 'aliens' available.
