Felt like I was part of an acid dream....someone else's. I'm so relieved to see the other negative reviews here, as I thought I was losing my mind. The audience lingered to watch the credits and I was stunned they weren't all running for the exits. I grew up in the 70s and COULD NOT RELATE whatsoever. There was zero chemistry between the lead actors. I couldn't care less whether they ended up together or not. And I get really bugged when they throw cameos of superstars into films and think we'll just go crazy for them...ugh. Sean Penn and Bradley Cooper should be ashamed. If I could give it zero start, I would.
