So many people LOVED this movie, I feel a bit of a compulsion to give my own review. I had three problems with it.
1. I generally don't like it when musicians cover other musicians' songs. Once in a great while, the new version has something to recommend or differentiate it from the original, but mostly not. I definitely *hate* it when poseurs or, gawd forfend, orchestrators cover heartfelt music, e.g. blues, r&b, rock. The reworking/overworking of the Beatles' tunes for this movie sucked.
2. I hate Broadway show tunes and the desperate over-orchestration that goes along with them. Not to mention the over-affected vocalizations and strained phrasing; but that's my third item. The changed tempos, changed melodies, and distasteful orchestrations sucked.
3. I hate hearing people with no heart and too many voice lessons singing heartfelt music. The main singers all well and truly sucked. Big time sucked. Hot-needle-through-the-eyeball suckage.
Joe Cocker was fun. Salma Hayek was, as always, a true hottie.
There's an old, probably apocryphal, story about someone asking one of the old delta blues guys if anybody in their group could actually read music. The answer goes: Yeah, some of them boys can read music; but it don't hurt their playin' none.
Everybody involved with this movie can no doubt read the shit out of a musical score and probably talk all night about music theory and all sorts of other music-related intellectual shit. I'm sure they all been singin' since they's babies and got work before they're two. [Identify the rock allusion and win a prize.] More voice lessons among that group than you can shake a stick at. It's musical as all get-out, I'm sure - intellectual, abstract, sophisticated, orchestrated music; but it ain't from the heart. And that means it ain't rock-n-roll.
If it ain't rock-n-roll, it ain't shit.
