'Joe Kidd' is solid.
It's not Clint Eastwood's best work but it's still a role that sufficiently entertains. You also have an important role for one Robert Duvall, who did 'The Godfather' in the same year interestingly. No-one else really stands out; not even the miscast John Saxon.
The plot is a simple one, which thankfully doesn't drag thanks to a short run time of around 90 minutes. There's also an amusing scene involving a choo-choo, so there is also that. Overall, it does enough for me.
