It's competent as animation , but, from the my perspective formed by old school Warner Bros slapstick (Bugs Bunny, Daffy), it's not good.
Problems for me (which may not apply to you):
- The Bunny is uncanncy valley nightmare fuel.
- Too much psychopathy on all sides.
- Death is immediately established as real, which breaks one of the foundational rules of violent slapstick (death is not real) so I can't relax enough to enjoy the shennanigans.
- There really isn't too much shennanigans, just standard traps and warfare without much comic exaggeration or setup/payoff. A roadrunner cartoon'll run through a bunch of outrageous and crazy scenarios in just a few minutes.
If you're not into the really old handdrawn stuff, have a look at Ice Age for how to make it work (is Ice Age digital?)
I'm reminded of an artist recruited to work on the original Jurassaic Park. He had been a hand-animator and said he didn't know anything about computers. " No problem," the recruiter from Speilberg's outfit said, "we can teach artists to use a computer, but we can't teach programmers how to be artists." This artist was responsible for animating the charming animation between the two velociraptors as they negotiated who was going to go in first.
Buckeye Bunny seems to be more a technical demonstration without much in the way of the creative flair that is the soul of the genre... and it makes sense they're probably using this to showcase standard use case and workflow. But sometimes you have to break the engine to get what you want, like Puss 'n' Boots: Last Wish scene where they are cycling ownership of the map and the landscape keeps changing--bonus audio track confesses that was only possible after seriously torturing the engine.
