Avoid this straight to DVD film
This is like all time travel films except all of the action has been removed. It borrows from buterfly Effect (the mother sad and depressed) and Looper (ending) but has nothing but talk for an hour and 25 minutes, just a five minute confrontation.
It is mostly the little guy talking about solving an equation that his father used to travel to 1946 to meet einstein. Apparently, building a time travel machine is simple, you just need an equation to land at the right place and time.
