I don't have the smarts to argue safely on this subject, but this guy's got some great graphs going on here:

What do you boffins think?
I stopeped following Lisi's idea on 2008 or 2009 or something like that but I guess that the consensus is that his program won't just cut it.
You can read about it on Distler's blog Musings: http://golem.ph.utexas.edu/~distler/blog/ (at one time he and Lisi exchanged very good banter back and forth and it was evident that Lisi himself didn't fully understand some of the more technical aspects of modern quantum field theory), if you want I can get you the said posts and you just take a look at the comments.
Another good blog to know why Lisi's program can't work without a major overhaul is Not Even Wrong by Peter Woit. Once again if you like I can give you some links and then you read and tell me what you made of it.
If I'm not mistaken there were also some good posts on the n category café on why Lisi's program is at fault.
There was a lot of buzz on the physics blogosphere as this was truly happening but I feel that these three blogs I talked about are the best ones for people that aren't physicists (though Distler's blog gets pretty heavy and sometimes I'm not quite sure that I'm understanding what's happening)
Edit: take a look at this http://www.math.columbia.edu/~woit/wordpress/?p=3292&cpage=1#comments and links and comments therein.
Edit2: Read this comment very carefully: http://www.math.columbia.edu/~woit/wordpress/?p=3292&cpage=1#comment-69590 I think that this may be a very good intro for débutantes in these issues.
