I have a lot of affection for Parolini - he put a lot of effort and imagination into his films, even if the results were uneven, to say the least.
If You Meet Sartana... is in my top ten, and Sabata and Adios, Sabata would both feature in the top 30, I reckon (or top 40 at least). The opening of Return of Sabata is brilliant, although it goes downhill from there, and while God's Gun is poor overall, there are some excellent visual touches that show Parolini was still trying (and it's still demonstrably a Parolini movie - he had his own recognisable style, whether you care for it or not).
Sure, his films are lightweight, but the best ones are as entertaining as they come.
And he's a hell of a nice guy, as well, even if he is borderline bonkers.
