1. Will Smith
Saying the words "Will Smith" out loud used to encourage smiles on the faces of all who heard it - nowadays, nobody seems all that interested in what the Fresh Prince of Bel-Air is up to. Smith was one of the most bankable stars of the '90s and the early 2000s, of course, which makes his recent fall from grace even more bizarre - the man seems more interested in guiding his awkwardly untalented son into a family business. No thanks, Will. Let's go back to 2008 for a moment: Will Smith made Hancock and Seven Pounds, both pretty terrible movies, something he seemed to realise, given that he disappeared for four years until he came back in 2012 with Men in Black 3. Though that fairly okay movie suggested Smith was planning on getting his act together, this year's After Earth - which once again revealed itself as a star vehicle for his son - proved that wasn't the case. What happened, Will Smith? What's going on? I mean, it's okay, I guess, if you want to mould your son into a superstar, but your son is a horrible actor, and he doesn't have even half the talent or charisma that you do. The fact remains that, as of now, Will Smith isn't anywhere near as beloved as he was once upon a time, and that's mainly because he doesn't seem to know where to take his career. After Earth demonstrated that brilliantly.
