While "Killer Adios" is nowhere near the worst that the spaghetti western genre has to offer, I feel that it's mostly for those who are spaghetti western aficionados. It gets off to a good start, with a good opening credits song, as well as a flavorable music score that plays throughout. Peter Lee Lawrence also makes for an interesting anti hero of sorts, having some negative attributes but also some vulnerabilities. As well, the first half hour or so does click along at a good pace. After that, however, the movie kinds of gets bogged down due to two factors. The first being that there is not quite enough action, and that the movie becomes more of a murder mystery than a western. That last factor might not have been so bad had the mystery been treated less casually and with a lot less talk. Before you think I'm giving this a negative review, I'm really not - I enjoy spaghetti westerns, so I was reasonably entertained by this one. However, I will add that I don't think I'll be watching it again any time soon.
