Great film but....

First of all, the acting is great, the script is hilarious, the directing is also very nice. This is a very unique film. I have never seen anything like this done before, where the surreal shots (like the love scene, the scene right before the mother dies, when Teresa is with leanard in the cafe, when she she Jesus, etc) are so magnificently done and embraced by the characters. However, I didn't get the ending, as well as the whole part with Catharine giving birth to a chicken. Was that just her imagination? Or was it really a chicken, or does reality not matter? Actually, this film is very imaginitive, and maybe it's okay that I didn't get it. Whatever. It's just plain trippy.
