The films you mentioned are all perfect or close to it for what they wanted to be. Remakes are best when a film had the kernel of a great idea or some great aspects but had alot of weaknesses as well. “Thomas Crown Affair” with Pierce Brosnan was a great remake because the original had a great concept but was super-dated and McQueen was never right for the part anyway. Plus making Crown an art thief instead of a bank robberer added the right touch of whimsy. Bronson vehicles (I’m thinking “The Mechanic,” “Mr. Majestyk, “St. Ives”) are good candidates because, although Charlie was an undeniable bad ass, they usually suffered from crappy direction and come off today as very dated.
