I always love a good episode focusing on Mr. Burns. Unfortunately, this wasn't one of the better ones. I liked Burns getting ragdolled around in the prison, but the rest of it just seemed somewhat off. The Power Plant crew didn't seem to have the funny this week, either.
And the B-plot with Bart, Lisa, and ants didn't work for me either. Although I got a good chuckle out of Bart putting a Pop Tart in the ant farm.
I was really skeptical of this from the trailers. Now having seen it, I'll say that the story itself isn't anything special and too much of the humour falls flat. But... and this is a BIG but... The film is visually stunning.
