Interesting film

The time machine was definitely the most interesting film I have watched. I have so many questions about the time machine. I personally don't believe that someone can create a time machine to take you back in time or forward in time. And if we created such a machine, what would be the purpose of us using it? Could we go back in time to fix prior mistakes we've made? Can we go forward in time to view whats coming? If we were able to go back in time would our bodies change physically? Would we be the same age, just in a different time? I can go on and on with questions regarding the time machine and that is what makes it so interesting to me.
