Take Pirates of the Caribbean, swap out the pirates and sea monsters with cowboys and indians, and you more or less have The Lone Ranger, which I went to see yesterday.
Basically, its like a later (but still pre-90s) Pink Panther movie except that the movie's Inspector Cluesou is only bumbling and not a moron, which alongside Johny Depp being a ham and those "strange horse" jokes were probably the highlights of the movie. Seriously, it deserves props just for avoiding the trap that the Green Hornet dove right into and made the protagonist more than a wad of Zapp Brannigan levels of glory stealing, moronic, jerkiness (although it did help that the only competent people in the movie ended up dead by the finale). That said, the unreliable narrator was both a hindrance and a help for the movie as it helped justify some of the goofiness of the movie, but the disjointed nature and occasional interruption/derailment really didn't do a lot to justify having a narration that isn't revealed that the end and the time spent on the interruptions/derailments could've been used to patch some of the plot holes (like how they found where the dynamite was hidden, or the lack of a meaningful conclusion to the 'become what you battle' subliminal message).
The tl;dr is that its a serviceable movie but not really anything more than that.
