Since Par 4s are my favourite "pars" in golf, I have no choice but to like doglegs, whether severe or less sharply angled, since there sure are a whole lot of them out there, especially on the courses that I tend to play.
Now, I think I understand why/how certain given sites and circumstances encourage architects to design doglegs; and, as I always have to grant, while I've played a goodly number of courses over the years, few would be considered in any way special or make anyone's lists - so your experience may be different than mine.
But here's the trouble with dogleg Par 4s, the way I experience them: almost invariably (indeed, almost by necessity and definition) the "turn" of the dogleg is the point from which a golfer, any and all golfers, will get a clear view of -- and hit his approach to -- the green. And, since the rules and traditions of "Par 4s" are very well established, every golfer expects to be able to get to that "turn" in one shot.
And so: in dozens of rounds at my local course (which has a lot of doglegs) and paired up with a hundred other golfers like me as we've played hundreds of dogleg par 4s, I have never, ever seen anyone (including me) do anything but pull out their driver long before getting to the tee and then blast away, time after time after time, aiming right at the centre of the turn and hoping for the best.
Now, my local course is fairly wide open, and on a couple of holes there are bunkers on the inside of the dogleg that one might try to fly over, but a) that amounts to essentially the same thing in practice and b) soon gets monotonous -- after all, no one is doing anything other than, as per above, pulling their driver and blasting away.
Is your experience of dogleg Par 4s different than mine?
Are there ways to mitigate this seemingly inherent trouble with doglegs?
Does it come down to a terrific green being the only element/quality that can differentiate one dogleg from another
