Plenty of action and almost lives up to the others in the franchise. However, not to be missed or overlooked as one of the btter robot wars themed movies.

I've bought several air beds from various manufacturers. I bought one identical to this one 1 1/2 years ago. It was comfortable but lost air after 3 months. I justified this as the user may have not taken care. However, I now believe its the brand. This one would not inflate at all. I will not buy this brand again. I've had great life from a better brands.

Ex Output:
Negative

This program is as wonderful this year as it was the very first year I saw it. I watched it on my Kindle Fire last night and could not get over just how clear the picture was and how crisp the sound was. I enjoyed and appreciated the extra programing after the main show, but the newer shows will never be as good to me as the original! I actually missed the advertiser and advertisements that sponsored the program in the first years ;-)Streaming this from my Kindle to my TV will allow for the rest of the family to watch...and did you ever think, when you watched this for the very first time, that you would watch this on your own personal TV (tablet/android/phone) and then stream it to your big screen TV? I know I never would have dreamed of such a thing!
