I wouldn’t say I don’t like it as such - I own the Blue Underground DVD - I just like a lot of other Spags more. I recall seeing it for the first time and within the first ten minutes or so thinking, wow, this is going to be a new big favourite. It’s very well made. But then it begins to meander, eventually losing its way (or, at least, losing my interest) altogether. Also, I was probably somewhat unfairly expecting something more from the sequel to The Big Gundown, one of my favourite westerns of all.
That’s just my opinion though. Generally speaking it’s a well-liked Spag and for good reason.
