Herzog doesn't spend a lot of time on things, which is good, I suppose, because that way we get more Herzog. But then again, if he would have known ahead of time that he was going to get the performance from Nicolas Cage that he got he might have spent a little more time massaging the script and he might have produced a masterpiece. Instead what he gives us is a pretty good movie with a masterpiece performance from Cage. The film comes off as a series of vignettes rather than a smoothly flowing story. A lot of it is rather implausible if you stop and dissect it so maybe a series of hallucinogenic impressions was the only way to go. It's a great film but it's not a masterpiece.
