The animation is definitely nothing to shout about at all, HOWEVER I actually found it really hilarious. It was like early family guy before 99% of their humor became completely non-sequitor and the characters warped unrelateable hyperbolies of their original personalities. I really like the family in Bob's Burgers, and each character has something I love about them. I only saw like three episodes but immediately got their whole dynamic and really dug it. The mom was a character too, she wasn't just "THE NORMAL ONE" of the family.
At first I was like "these voices don't seem to match the characters AT ALL" but once I got comfy with it I really dug the awkward voicing. It just fit the tone somehow I thought.
My favorite character's Louise, voiced by Kristen Schaal
which is awesome!
