Paprika is a 2006 animated film directed by Satoshi Kon. It's won all kinds of awards, and I had been looking forward to seeing it, but I fell asleep during it and drifted in and out.
Moria calls it "Satoshi Kon’s most beautifully animated film" but thinks "In truth, the ideas that Paprika has are old hat." Slant Magazine gives it 3 out of 4 stars. DVD Talk says, "Its experience gets deeper upon reflection and there are numerous moments that will linger in your memory for months to come" and calls it "truly inspiring entertainment". EW gives it an A-. Rotten Tomatoes gives it 83%. Metacritic gives it 81%.
