This connection is just inside the MCT for CLT, but it is well outside the SCT (Sensible Connection Time) for anybody who has a tight schedule. Having nothing to do with the schedule, this is a poor choice. Not much OP can do, but this is important for others. If OP misconnects, he has at least a 2-hour wait and a 4-hour wait if the 2-hour wait flight is sold out.
