forever young
I just saw this and although it wasn't bad I felt that it could have been better. The acting was good but the script let it down, the narrator became a bit annoying.
I started thinking of films which have dealt with the idea of immortality, never ageing. One decent film came mind, forever young with everyone's least favourite actor (now) Mel Gibson. I personally enjoyed it more, of course there is also Highlander, the first was a good film, although rather dated now. It dealt with the idea if never ageing really well and what the repercussions of it would have on a person, mind you the others were just terrible.
