I give Yeti 4/5 giant nipples. It was, shockingly, a good movie, even if dragged in some parts and the rampaging bits didn't make much sense.
The music varied from "amazing" to "mildly annoying". I liked how the Yeti and the eccentric businessman were tragic characters, as was the professor, who was ruined by his desire to have a nice nap. The practical effects were neat. Also, it had a dog.
