Ends up, it was pretty good ... the story resembles "Forrest Gump" - and whatta you know - Eric Roth who also wrote Forrest Gump penned the screenplay. In critical reviews - the movie was even called "Forrest Gramps".
Forrest Gump is one of my favorite movies - this movie has so many of the same elements and same "dumb southerner accents" that it's hard to get Forrest Gump lines out of your head while watching it.
Here's a summary from IMDB:
... a man who starts aging backwards with bizarre consequences.
The makeup and special effects are groundbreaking but surprisingly might have been honed in "Little Man".
I suppose the story might have more significance to you if you've ever dated a significantly older person ... such as I have. There's an interesting dynamic regarding this scenario.
I enjoyed it and I'd recommend it ... I'd maybe just wait for it on video if you've missed it in theaters so far.
