5-hour drives can be long and interminable, or gorgeous and somehow fly by. The first 3/4 of the drive to Calgary are of the second type. The last hour is a bit boring, but not awful.
Most people who think a 5-hour drive is long think nothing of sitting in traffic for 4 hours a day, getting to and from work. (Does not necessarily apply to you)
Perspective.
I would rather spend 3 or 4 hours driving, than sit in a movie theater for 2 to 2.5 hours, but I get that I'm not everybody. That's cool, but if you are like me, and love time behind the wheel, then this is an amazing spot.
*Elk picture is not actually on this highway. I see similar elk herds on this highway on most trips, but don't have my pictures with me.
