On the one hand, you have two fine, venerable actors in John Lithgow and Blythe Danner. If you are fan of Danner, as I am, you might wonder why she so rarely appears in movies you'd like to see. I probably enjoyed her most in the TV series Huff. Point is, I'm glad to see her name in the credits for The Tomorrow Man, but I don't get my hopes up.
Next, you have writer/director/cinematographer Noble Jones (what a great name!), who makes his directorial debut after working mainly on music videos. He has worked (been mentored) by David Fincher ... he's not a novice. And he seems to have inspired his veteran cast. If had to summarize, I'd say Jones looks to be an intriguing director and cinematographer, but the story didn't do much for me, and the ending simultaneously came out of nowhere and yet was highly predictable. The Tomorrow Man is ultimately harmless, and I'm not sure that's what Jones was hoping for.
So my wife and I, both in our late-60s, were clearly supposed to identify with the geezers on the screen, but they didn't resemble any actual people I know. (One exception: Blythe Danner's character's house is as messy as ours.) Jones got The Tomorrow Man made, and that's no small accomplishment. But he hasn't yet made his first masterpiece.
