Yes, you are not alone. I actually do not have high hopes for the movie. I think that the only hope might be if they take a somewhat satirical spin on it. It really was such a great show, but probably best to be left back in the 70's. Today, I am guessing that they would probably create what is essentially a 4th sequal to Jurrassaic Park, which we clearly do not need. Who knows, maybe I will be pleasantly surprised. Don't get me wrong, I will definitely go out and see it, regardless of what I my predictions are. Now that we are chatting about it, I am going to see if there is a box set of the episode that I can buy.
On a side note, you can watch all of the full episodes of Speed Racer on Hulu.com
