The entire movie takes place in Stephen's flat. And in his head. Stephen hasn't left his flat in a year. When mice throw off Stephen's daily routine, he remembers a road trip with his friend Bunny. The road trip comes to fruition through Stephen's confronting the girl he fancies, who says that he's in the friend zone. Stephen, through Bunny, realizes that he needs to go on a trip to recoup from his unrequited love.
Stephen continues mulling around his flat, finding different articles that remind him of his road trip. Characters from his trip manifest themselves in his flat too, as Stephen hallucinates. The remembrance of the same event that caused Stephen to retreat into his flat a year previous leads Stephen to make a decision with his life: to live or not to live his life.
I thoroughly enjoyed the aesthetic elements of the movie, from the paper scenery in Stephen's remembrances to the hallucinations wearing Stephen's robe in the "real world." The plot was well-developed, but not as immersing as it could have been.
I would rate Bunny and the Bull 7 out of 10. It was a good movie, with good acting, inventive directing, but a rather lackluster plot. It was intended to be a comedic film that would make you laugh. It worked as a comedy, but wasn't as deep as it intended.
