Maybe I was just in a bad mood... Perhaps I'm being overly critical here, maybe there were other circumstances that made me dislike it, I just don't know. There are certainly more than a few positive reviews here referring to this film as a "cute sleeper," but I just thought it was more cheese than content. Of course I think Peter O'Toole and Joan Plowright are fantastic actors worthy of all the accolades they receive, and I do think that Alicia Silverstone is talented and worthy of note, but the script is really where the film falls short. Suffering from a bad case of "do people really talk like this?" the movie treads into the common unfortunate territory of miscasting likable actors as alternately snotty yet lovable rock stars and forcing them to say lines that literally fall out of their mouths awkwardly. A specific moment early in the film when Silverstone's character has a fight with the band's rhythm guitarist and the drummer, whose consistent pot smoking is played more for pathos than laughs, insists that everyone calm down and "smoke some doobs or do some yoga or something." What? Despite being in the English countryside the drummer has a seemingly bottomless supply of marijuana. Ordinarily this would be the source of humor in a broad comedy, but this film seemed to just show it matter of factly. Here's the drummer, and he's smoking pot, that's how you know he's the drummer. It seems a little heavy handed, not unlike the heavy hands that must have been running the camera, as several shots have a very sloppy over the shoulder feel to them, but it's used to no effect, other than to jar the viewer.
On the upside the songs were decent, and everyone honestly seemed to be trying to make the best of a bad situation. Not unlike watching a regional theater troupe slogging through a lame adaptation. At least they seem like they're trying to make the most of it. It's hard to say really. I don't know if it's worthy of renting, but give it a look if it's on cable. Who knows? Judging by the online reviews you're more likely to enjoy it than hate it.
