^I am not a big fan of station overbuild anywhere, TBH....but building "grand" stations downtown would likely be prohibitive from a cost point of view...land is so much scarcer and, as a result, more expensive.
I guess, in the remoter areas there are two aspects to the "grandness"...stations need to be noticed for people to get/accept/realize (whichever word works) that transit is there...and, I guess, from a creature comfort point of view the need to make transit attractive and "nice" to use is higher.
Still don't like it, but it is no surprise to me that the "grandness" is more to the outskirts than DT.
