I had some expectations after reading all these favourable comments, expectations which weren't fulfilled by this routine western.
Like in most of these ordinary SWs the 1st half is the best part of the film. The directing is unimaginative and flat looking from the beginning on, but there are at least several appealing story elements.
Especially Steffen's scenes together with the saloon singer are nicely done and promising. But like all the other things the film promises, nothing is redeemed. There are lots of plot holes and unexplained story elements and relations between the characters which are carelessly given away. And the film doesn't give me the notion that this is something else than inattentiveness.
Director Rosso was a one time director, and I have no doubts why he didn't made another film.
Steffen's first action scene is a good and effective one, but the rest sucks and in the 2nd half the shoot outs are as bad and boring as they can be. Maybe better than in Apocalypse Joe, but only for being shorter.
There is also some praise for Eduardo Fajardo, but for me he only gives a routinely oily bad guy performance. In contrast to Steffen he could do better if required (his last scene is notably weak for directing and acting). So the women have easily the best parts of the film.
The similarities to And God Said to Cain are so sketchy, that if Margheriti had changed the names (which are btw far from impressive: Acombar, Gary Hamilton and Santa Maria brothers), nobody would have drawn a connection between these 2 SWs.
All things considered A Stranger in Paso Bravo is best described by stating that Anthony Steffen again wears his too small hat.
