Once upon a time in Mexico

I watched this last night and was pretty mystified really. Not by the plot which (I think) I managed to follow but by the tone. I just googled it to find out if it was meant to be a comedy or a straight action film, apparently the later. Because that's what puzzled me, bits of it seemed to be intended to be funny and if they weren't were laughably hammy, yet other bits were extremely dark and the last half-hour was clearly just a shoot 'em up action film. It occurred to me while I was getting dressed this morning and mulling it over that maybe it was a Tarantino type thing - hugely violent but black comedy too. Perhaps it's just that since spy kids I have trouble taking Antonio Banderas seriously.

p.s. I wish the mood list just once would have the word I wanted on it. Obviously you can't be puzzled on lj, or apprehensive.
