The cast list alone semaphores the message that this is an EBGAC (everybody got a check) movie, the sort where all the available character actors in the waiting room got a chance to do their shtick. The script is the classic Hollywood "melodrama" diluted for commercial-interrupted TV. Stirling and Hy start out slow with cut-out characters and stock situations and then push them faster, through, past, around and beyond the actual "historical" situation that is supposed to be the excuse for this miniseries.
I don't know how many nights this thing originally ran, but I watched it on VHS in two installments. While I originally began to watch it to laugh, by the time it was over, I was thoroughly caught up. There are cartoon characterizations and a lot of odd anachronistic social comment, as well as some blatant emotional button pushing. All in all, everybody did their job well, earned their check, got another credit on their SAG CV, and by the time the final credits rolled, I felt that my time was not wasted.
