Given the relative obscurity of this I didn't expect much, but it's considerably better than a lot of 70s Italian crime/cop thrillers (and indeed feels more mid-70s despite being a few years older).
As for a prior reviewer's complaint that there's not enough Klaus, well--of course you have never have enough Klaus, but while he doesn't appear much in the first half (and then only in isolation or with a girl, never with the other main actors), he dominates much of the second half as a cold-blooded killer who muscles in on the protagonists' bank robbery after it's a done deal. Klaus doesn't get a lot of dialogue but he's fascinating nonetheless, making his character shift constantly from an icy, complete lack of empathy to (any time he's threatened himself) complete cowardice.
The rest of the cast, playing the motley crew of heist conspirators, are a fine assortment of 2nd-rung Italian lead and character actors from the era, plus the usual couple Eurobabes with decorative if thankless roles. The script is above-average, the direction more than competent, the whole thing pretty consistently interesting and well thought-out if never wildly original. The one very 60s element is a couple scenes at a psychedelic discotheque (the music throughout is very good, both instrumental score and songs).
The big minus in the cut-rate old VHS I watched was that it was full-frame, and this was very clearly a widescreen movie--sometimes significant figures or action were cut off. If I'd seen it in ideal form I'd probably bump it up to a 7.
Given the mediocre and derivative nature of many Italian crime flix that followed, it seems odd this quite good if not certifiably great one doesn't have a better rep.
