Yeah from what I remember, the outfield areas are sort of squared off and angled at points...maybe it was the grass the way it was cut and shaped by the warning track areas. 
The stadium from a fans perspective is what I was speaking from...amenities, food, facilities generally were pretty nice...The one thing that struck me funny there was sitting in the infield and looking to the outfield was the high wall behind the stands as it went straight up with little light. Whereas some of the other closed parks have tons of windows to add more light. It is also probably too large. From my perspective it wasn't a bad stadium but not great either...sort of just ok.

I've visited alot of stadiums and the worst ones that I have seen are without a doubt Tampa and Oakland with AT&T and PNC probably being the most unique look. The biggest disappointment was the Yankees new stadium as it just seemed ok and didn't live up to the expectations I had going there.
