Don't call it a comeback

I finished watching Inland Empire last night, and I did not like it. Mostly because I did not get it. Don't worry, there is no way to spoil it by me saying this: I did like how the descent into madness was portrayed, but I felt like the motifs did not really serve a purpose. Again, that's probably because I just did not get it. I had to read a plot summary afterwards just to be able to make heads and tails of it.
