^^ They could just use Charlie's son or something. Or an original Angel. It would still be the Charles Townsend Agency.
One good thing about the movies was that it was NOT a reboot, but dealt with new girls working for Charlie as if the agency has been trucking along all these years. A problem I have with reboots is trying to accept new actors in old roles that pretend the original never existed - I prefer the continuation.
This is exactly my opinion.
