The preview to this June 7 release is enough to make one ponder just what ends a career, or signals the beginning of the end.

Martin Lawrence was old news 20 years ago, infamous on my side of the industry (entertainment journalism) for being one of the bigger wastes of time — rude, self-destructive, an arrogant SOB of limited talent who was the last to get the memo.

Will Smith was always a nice, compliant, press-and-public friendly persona who put the effort into being liked. Until his little performative tirade at the Oscars. As indulged as he was during his many years “owning” summer, and his years chasing an Oscar that always seemed to be just beyond his talents and reach, you had to wonder if the public and the good press would come back.

Kevin Costner’s post “Dances with Wolves” divorce chased off fans. Russell Crowe throwing a phone (isn’t that quaint) caused him to jump the shark long before he let himself go to seed.

Add the public’s fickle attitudes towards stars to the fact that “Bad Boys” seems so…late 80s/90s — and we should be looking at a blockbuster that busts.

And yet this is almost sure to be a smash of the summer. Go figure.
