Query: Yet another tired time-travel story

I thought this book would have Crichton's usual blend of sci fi dazzle and high storytelling flair. Instead I got a dash of pseudoscientific babble (wormholes, quarks, probability fields, oh my,) mixed with another rehash of the old H.G. Wells script (Man invents time machine. Man travels to another time where things are more complicated than he expects. Many problems ensue. Man returns to modern era enlightened.) Yawwwwwwn.
