I can't decide how I felt about it. I think the easiest is to separate it into two bits: the movie-movie, and the "omg look how fucking stylish and awesome and trippy we are omg" visual bits.
Although I think I covered how I felt about those with that one line. And one addition: I'd been told, and was expecting anyway, that there was far more style than substance, and to some extent that's very much true. There were times I was getting sucked way way in, to the point where I was starting to love the characters I'd had trouble mustering up any care for, and BAM some stupid surrealist LOOK HOW FUCKING HIP I AM arty crap would pop up and knock me right out of it. It was too jarring.
Movie-movie wise, I liked it. The plot was cliché, but I love me some clichés, presented well and with characters I could get into.
Problem being I just could not get into Lucy (and, to a lesser extent, Jude - he was an excellent foil for Max, but ugh not a main character at all). It was equal parts dislike and disinterest WHAT A FANTASTIC COMBO.
I loved Max. LOVE LOVE LOVE LOVE LOVE. OMG. Loved. And Sadie, and JoJo (and OMG the Let it Be scene was OMG), and OMG PRUDENCE. Even if she totally wasn't in it enough to even have a purpose I LOVE PRUDENCE.
There was a point at which it switched from a really enjoyable ensemble movie to a Jude and Lucy movie, and I felt somewhat cheated, because it was the ensemble and the mix of stories and all that hooked me, and suddenly I was left with Spoiled Princess and Captain Blando.

But OMG YOU GUYS Bono was OMG OMG. Also: OMG.
In short: If you can get past the OMG WE'RE SO ARTY, and the biiiiig stretch of "hey let's make the blandest supporting cast the main focus for a while", and you like musicals, and Bono, and are a sucker for a happy ending, it's reasonably worth it. That's a lot of ifs.
