My take on this game?   I watched the whole game on the  X3D  site. 
(I also popped in and out of about a dozen other sites.) 

The choice of the Slav/Semi-Slav by Black should have done well. (Fritz did very well from classical positions against Kramnik.) But Kasparov counters with the ultra-sharp play, 7.g4!?. ( Maybe - '!!'  If he had lost this game, I am sure  everyone  would have roundly condemned this move! )  But Kasparov has come well-prepared  ...  the experts tell me the computer was OUT of its {computer} book before move ten!! 

Move 13 was possibly new, I could not find this move in any of my books, my database or any on-line database. (Hillarp-Petersson  had previously played 13.Kb1.) 

I thought b5 was a gross blunder. (At that level.) An Internet student of mine has a brand-new (Pentium IV) computer and was running  Fritz 8.0.  He said the computer already considered White to be clearly better. In any case, I feel ...b5; definitely made White's job easier. Kasparov played very sharply and accurately. The move 17...Re8???; must have been the result of some type of power surge or a hole in the program. After this move, the computer has ZERO chance of defeating a player of Kasparov's caliber!

The game did NOT live up to the hype. But I warned everyone, Kasparov will come prepared armed to the teeth. All holes in the opening book will be discovered. Any trends or tendencies of the program to play poorly in certain types of positions or endgames will also be fully exploited. ( I wonder if there is any truth to the rumor that hundreds of Russian Masters were given computers and Junior 7.0, and asked to play games against the computer program?  { ---> To look for any possible weakness.} )  

Hype and rumor aside - this match is looking like a blowout. Of course, I predicted the same thing when Kramnik was far ahead of Deep Fritz, I will be more cautious this time. I think a final score of 4-2 is completely reasonable ... at least up to this point.

Kasparov wins game one against computer
27.01.2003  Deep Junior is one of the strongest programs in the world, and it was prepared for this match by human grandmasters. But in game one in New York it ran into a Super-Grandmaster, or something beyond that. Garry Kasparov took the bull by the horns in a daring game which left the audience gasping.
