Last 20 Minutes Turned into 2001: A Space Odyssey

So...I was following the movie up until the final 20 minutes or so where we spend majority of the time in what I can only purport as being astral plane travel?

The movie was all right as a surrealistic visionary piece set within the Wild West motif, but just after the halfway mark I started getting the feeling that I was watching a Terrance Malick flick, and I really don't like Terrance Malick. Worse yet, the final part of the film -- or rather, the "confrontation" -- felt like it was just one big, long homage to 2001: A Space Odyssey's long-winded ending.

On the upside, at least this film's acid trip scene at the end had some bearing to the plot and laid groundwork to follow-up dialog that explained itself.

I just didn't get the the movie as a movie...it was pretty shallow, really. As a few other posts mentioned, it was also quite pretentious.

If the movie was going to go that deep into the whole shamanism thing, the least they could have done was made the main character slightly more tragic so the audience didn't come away thinking..."Uh, that was it? That's what was bugging this guy for so long and fueling his quest for revenge? Seriously?"
