Before watching the movie I logged on to IMDb and looked at the user ratings just to check what I'm headed towards.After looking at the poor ratings I was put off and didn't even want to watch the movie.But I am not one of those people who need ratings on a website, other peoples' opinions to watch or not watch a movie.And I only declare a movie "GOOD" or "BAD" after actually watching it.So I watched it and much to my surprise, all things considered, it is a pretty good effort. So what if the special effects are not too good the whole idea of evolution and time travel works for me. Yes I too don't believe in evolution, but that is what movies are for. If all you people who voted 1 to 5 for it think it is that bad i'd suggest you watch documentaries from now on as by voting this low for A SOUND OF THUNDER you insult the essence of the word 'MOVIE' and their-in imagination itself.Granted his movie has its flaws but it deserves at least a 6 rating, no matter what anyone says.
