Funny, it seems like Bob hated the movie for all the same reasons as I myself enjoyed it.
I think Johnny Depp works well as Tonto. He is clearly giving the character all he's got, which as usual is very nearly enough to carry the entire movie himself. Besides, the Tonto character has always been, to some extent, a stereotype. Casting Depp is a perfect way of not only acknowledging this, but also make the most out of it.
As for the Lone Ranger, we must keep in mind that he started out as the unfailing, one-dimensional hero of an adventure series in 1933. He is the classic all-American, dime-a-dozen, white-hatted, Colgate-smiling, squeaky-clean idol of wide-eyed children everywhere. He is a gunslinger who always outdraws his opponent, and never misses. He is the white in black-and-white morality. He is the centerpiece of a fictional world specifically tailored to accommodate his boyscout philosophy.
He is a cowboy who has never stepped in a cow pie.
What do you think would happen if this character was removed from his usual surroundings and plonked down in the Old West as it is portrayed in more modern media? Yeah. They haven't changed the Lone Ranger into a parody of himself. All they have done is change the world which surrounds him. Most of the movie is a fish-on-land story, with the Ranger stumbling through this strange new setting, determined to survive and persevere either entirely on his own terms, or not at all. And in doing this, he manages to play both the hero AND the fool. Respect.
Is Tonto a mystic or a madman? Is he right about Butch Cavendish being a wendigo, or did he simply lose his mind along with everything else that Cavendish took from him? I think the movie is actively trying to make this as ambiguous as possible. Notice that the silver actually IS implied to be cursed, as seen when the Ranger picks up a lump of it in Red's saloon. The tribesman who reveals Tonto's backstory clearly leans towards the "madman" theory - but he doesn't seem to care that much about Tonto, nor know him very well. Yes, there IS every chance that Tonto simply sees Cavendish as he wants to see him - but by the same token, it is also entirely possible that the tribesman is oversimplifying his own view of Tonto!
Certainly, Butch Cavendish is a human being. But he is also a monster. Disfigured, greedy, even cannibalistic - he might well have stepped right out of someone's nightmare. We never really find out if he is possessed or not. A fancy CGI wendigo like Bob asks for, would have eliminated all doubt - and wouldn't have been nearly as scary. Paradoxically, Butch Cavendish's humanity is the most menacing thing about him.
In short, damn near everything about the movie is widely open for multiple interpretations. Did the Ranger come back from the dead? Is the horse an emissary from the spirit world, or just the horse equivalent of a total weirdo? The Lone Ranger may well appear as a different movie to different people, and I think that's an awesome thing to pull off!
This movie has done the impossible: Introduce the ultimate Western adventure cliché to a modern audience in a remotely believable fashion. It is a bit rough in places, but it WORKS. It is funny. It is thrilling. It is everything an adventure movie should be.
And I, for one, would heartily recommend it.
[small]Also, Depp's interpretation of Tonto bears an uncanny similarity to the acting style of Buster Keaton. I suspect that this may be intentional, as the climactic train chase apparently owes a lot to Keaton's 1927 masterpiece The General - complete with dangerous debris on the tracks, a sabotaged bridge, and a single man hijacking a train and creatively fighting off pursuers. This MAY have swayed my view of the movie somewhat - but I did enjoy the other stuff, too![/small]
