I just watched the "Dorado" release yesterday and felt the same way. For a Spaghetti Western it had a lot going on story wise. Lots of characters and sub plots to keep track of. I found it to be a bit confusing at times, but usually knew what was going on.
I felt the music was standard 60's/ 70's stuff. Not that great but not horrible either. It would have been decent for any other movie of the time, but quite a let down as far as Spaghetti Westerns go.
It took it a while for the action to get going but when it did, it was certainly entertaining. As already mentioned the scene where he was hanging from the rope was hilarious, the gory scene where he dug the bullet out of his hand was awesome, and the dynamite in the mine was entertaining.
I didn't think it was a fantastic SW and certainly not one of my favorites, but it had its moments. It seemed to have a bit too much going on that dragged it down to an uneven pace.
One thing I really REALLY appreciated about the movie were the framing of some of the shots and some of the transitions. They were really well done and probably some of the best I have seen in a SW. There were several that really made an impression on me:
The first scene was at the beginning where the camera is exploring the fort and then suddenly a knife pops up into view. You not sure what to expect, and then you realize that it was a guard and he throws it down onto the table. It was well placed and helped the establishing shot explore the fort smoothly.
A short while later there is the scene where Tarpa's men are going after the 3 people sent to protect Gatling. One by one they break into their rooms and when they get to the third room they kick open the door and it cuts to them flinging the door open to Tarpa's place and telling him the job was complete. That was an awesome transition that added a lot of punch to what was going on.
Then there is the odd scene afterwards where Tarpa and his "boss" are talking about witnesses and his "boss" is leaning against the mantel piece. His face obscured by his arms and the light from the fire flickering all different colors off his clothes as he speaks. In the background you could see Tarpa standing looking insignificant. An awesome shot to say the least.
Another shot that really stands out it when Tarpa goes to see his woman and tells her to wear the dress and he throws the dress at her. The film keeps the momentum of the scene moving when it cuts to her (now in the dress) being shoved into a gate/ banister.
The movie was very well edited at times, but at other times was just as sloppy. There was a lot of good stuff at work it just didn't always come together.
