I really enjoyed this episode - i thought the pacing was really good for a reality show. For once, it really felt like they were focusing on the parts that i found interesting - the sculpting was amazing, and i loved seeing the puppeteers before and during the screen test. The screen test was A LOT of fun!
But i think there was really only one creature where the eye seemed to move at all. I can totally understand why, given the time constraints and the number of contestants who seem to lack familiarity with the tech, but it's really remarkable what a long way eye movement goes to making a creature seem lifelike!
I think they were required to have one mech aspect so couldn't have just scrapped the eyes altogether
