One thing that has grown on me about Comerica (full disclosure, I haven't been in years, this is strictly from a TV perspective) - the backdrop with the Detroit Skyline in the background. It's never going to be Pittsburgh, but especially in our current era where Globe Life Field, with it's generic look and Costco-like atmosphere, is considered the model ballpark, there's something to be said about a ballpark located in the central business district of a city and not out in suburbia. Just more aesthetically pleasing.
Like G2, the dimensions of the ballpark are fine and generate more action than I think the park gets credit for, owing to the amount of room in the gaps and the possibilities of triples that don't exist most places.
