The scene where the two guys dine at a chic French restaurant is a classic and may have inspired a similar scene in The Blues Brothers some years later.
The theme music is not classic western but the lushness of the music suits the film.
I continually find Bambino's disgruntlement with his half brother to be a source of laughs and the slapstick violence works well.
The running joke about the two at first trying to rob, and then helping a travelling family works well. These two are seriously inept criminals.
If you enjoyed the first film (and I did) you will enjoy the second more and there is a lot of memorable comedy here.
