It's a time travel flick but for the more science minded among you, don't over think it and you'll still enjoy. You also get to see a kid give almost as good as Reynolds can dish out which was oddly satisfying. Then there's the soundtrack by Rob Simonsen to top it all off. I watched this last night and STILL have the theme from the end credits bouncing around in my head and I'll be honest, while listening to it and reflecting on my own memories of my Father... One hell of a lump in my throat for sure.
