In brief, this 2008 remake of the old series is just as good as the original only now we get widescreen, 5.1 surround, batter special effects and a better car in what looks like a black Shelby Mustang as KITT, able to transform into a different vehicle for attack mode, a 4WD and a submersible and even to recreate objects like keys etc with the help of on-board technology.
As usual for virtually any US TV series that I like, the plug's been pulled on it after only one season (just like American Gothic, Firefly, The Twilight Zone remake and that video game-based series I can't remember the name of). It seems to me that the US TV networks are simply obsessed with ratings and if these series' don't get them then it doesn't say much for the intelligence of your average US Joe. Presumably they exist on a diet of sub-soap rubbish as is often the case with GB TV viewers.
I loved the original when I was young and I love this just as much now I'm middle-aged. If you liked the original you won't be disappointed. If you've never seen the original, just buy this updated version as the lack of effects, widescreen and surround sound on the original may disappoint.
