The story was an interesting concept. It's about a man who finds out that he does not have as much control over his life as he thought he did. I personally thought that that it was good that he was able to regain control of his destiny. But, I feel that it could have ended better.
In the original Twilight Zone, the underlying commonality between episodes was the ironic ending (i.e. the guy who finally had time to read but broke his glasses). This ending was not ironic, in fact it was actually optomistic. Here's what they should have done.
Titus (I forget his character's name), gains control of his life and goes home to plan his future. But then, before he can tell his wife the good news, she shoots and kills him in a fit of rage. The irony being that Titus was in control of his own future, but his wife wasn't.
Now that, would have been a true Twilight Zone ending.
