I was really hoping that the rumor of this film being Smart's origin/first assignment was just a rumor. 99 more experienced than 86? Sigh.
Yeah, this is rather disappointing. I wish they wouldn't have done that.
Part of Smart's character is that he "thinks" he knows it all.
Ironically, in the new movie, Mazwell Smart mirrors Barbara Feldon't character in a first-season Man From UNCLE episode.
In that show ("The Never-Never Affair"), Barbara Feldon plays Mandy Stevenson, an UNCLE translator who years for the excitement of espionage. Napoleon Solo, feeling sorry for her, invents a fancy story to make it seem like she's going to be an important courier when she's really getting Mr. Waverly's pipe tobacco. Through a quirk, she receives an important microdot and now both the heroes and villains are trying to get to her first.
In this movie, as I understand it, Max is an analyst who yearns for the excitement of espionage, etc.
For me, in the original show, you didn't try to explain Max. He just *was* what he was -- bumbling in some ways but somehow he could always handle himself (the fight scenes were reasonably well done). It's a contradiction. You don't explain it. It just IS.
