Really appreciated a lot of what Blow-Up was doing on a thematic and intellectual level. I wasn't prepared for it to be such a meditative, cynical statement on the production of art and ego but I liked the ideas explored.
I will say though I got a bit filtered by the emotional barrier the film had up, I just wasn't able to connect with it beyond saying "huh, that was interesting" afterwards.
The scene at the rock gig was class though, really felt like a thesis statement for the whole film!
