Are you basing that opinion on that picture? Oh, get real!
How many terminals (modern era) look worth a crap from the cockpit?
The front looks just fine and, most importantly, the access for pax is virtually instantaneous- no traffic fight (access is NOT by the main DAL feeder); you can drive up five minutes prior to flight-time, and make your plane no sweat. I know, I did it.
And the gate areas are luxurious, computers and phones available for use pre-flight, coffee and snacks, and a security check point dedicated *only* to Legend pax.
The separate terminal thing is good for saving twenty to thirty minutes, easy, at both departure and arrival. To my eyes, that makes Legend's terminal a beautiful gem.
