I've watched it twice, once alone and once with my brother. My brother liked the good, the bad and the ugly more though. I prefer this one despite the more linear narrative, though I've enjoyed all movies from the dollars trilogy.
Ennio Morricone's soundtrack also plays perfectly into each scene. The Musical Pocket Watch that El Indio holds, its soundtrack, is beautiful and daunting at the same time to me... And the way it fits into the scenes of the Indio's murderers is masterfully done too.
Like, the 0:18 seconds sets the tone for a reversal, like the final duel. The 1 minute mark sounds like that Dracula type piano stuff, setting a daunting moment highlighting the cold blooded killing moments... The way the direction is played too, focusing on their expressions as if in slow motion, with the expressions (mainly El Indio's in the final moment dripping a tear) is fantastic. He's a cold blooded villain but the disturbed past, even though fruits of his own mind's disturbing thoughts (perhaps a sense of not belonging or abondonment... I think it was left kinda open), sets him apart from just an average villain... Very good, I may even re-watch some scenes again now.
