The promise of the series has been better than the fulfillment.
Some of the programs, particularly those hour-long ones, have
been ludicrous (A Neronian word?) and chaotic because of the
condensation required to fit the time limits. This particular one
belongs to the better installments.
As has been mentioned before, Maury Chaykin fits the description
of the part but is less than commanding even as Timothy Hutton is
fine. Perhaps Thayer David was the best Nero but he did only one
installment before his untimely death (Perhaps a result of the
previously mentioned physical requirements for the part.). William
Conrad, I thought, was twinkly and simply awful.
The others are fine in their recurring smaller parts and the series
has the proper period feel of the novels.
