@mysteryman,
I'm a long time fan of Lopez and know the film story pretty well.
I'm a long time movie buff, though not so much lately. I used to follow Pauline Kael's movie takes, not because I blindly follow critics, but because whenever I'd seen a movie and then her review, she was spot on re my own opinion most of the time. So, if she reviewed something before I saw it, I would keep her comments in mind but be open to disagreement. And that mode has been my way for the decades since, re checking critics' views.
The negatives I've picked up about the Soloist would likely grate on me too; for example, from Kenneth Turan in the LA Times, a couple of days ago. I won't link that so as not to be a 'spoiler'.
Will be interested to see what you all think.
