Godsend (2004)

You'd think by now that other characters would have learned to be wary of Robert De Niro when he is in his do-gooder mode a la "Angel Heart"; it always ends in tears.  Here Greg Kinnear and Rebecca Romijn-Stamos have lost their eight-year old son in a freak accident.  Kindly scientist-doctor De Niro manages to convince them to move to a new locale and to let him illegally clone a new child, but of course he has his own agenda or there would be no film.  Everything is fine until the new son turns eight, and then....  The movie feels long, is irrational, has a few feeble shocks, and no discernible ending.
