Well, Eastwood's rich career has its low points, too, and this 1970 bummer certainly qualifies as one of those. It's a dull and disappointing Western. The main problem is the thoroughly uninvolving story - so uninvolving, in fact, that it makes you wonder why exactly the filmmakers chose to tell it and if they thought it had any interest whatsoever. Eastwood himself is OK and occasionally enjoyable, but MacLaine is horribly miscast.
