Boy did I want to like this film. Being a big fan of Heinlein and time travel stories, I truly believe it's only a matter of time before we figure out how to do it....which means we are already experiencing ourselves (of the future) doing it right here in the present. So THAT is NOT my problem with this film. Instead it's the ridiculous notion of the entire story and the actions that ALL of the different characters need to want to do in order to make the story even possible in the first place. It's very much a chicken or egg story and it's just plain silly. Truly ludicrous and unrealistic. A big disappointment. Although the acting was very good.
