To wrestle this thread forcefully back on topic...
He had a different look for almost every film. I liked his look in Above the Law, for example, better than Hard to Kill; OFK and MFD about the same. Under Seige (both) were good, the first one I liked his look slightly better than the second, though (don't know why, I just did). Despite health worries from extra weight, FDB and The Glimmerman were looks that I liked, as well as HPD.
He looked just plain awful in both OFAK and BOTB - unhealthy, like he'd had too much good living and not enough clean living. In those two films, he did not look like he was taking care of himself, at all.
The rest of his films - okay by me!
So, for me, I don't think any era was best, best - although the 80's-early 90's seem to be the best overall.
