I strongly agree! They treat GR like it is something written under the influence of QM with all those complicated and twisted notations which look more alike a difficult matheamtical guide for GR than a book that provides reader with the usual litrature of GR! For instance, D'inverno, Weinberg and Hobbson use a quite simple style to express things and are more helpful than MTW just because the latter uses unnecessary explanations and prolongated proofs\derivations which if were neglected, the book would end at page 500!
There are lots of thin books that can be more fruitful than MTW for an interested reader. If you are after a preliminary book in the context, go with D'inverno, Hartle, Ohanian or Schutz. If you are looking for something much harder and up-to-date, try Weinberg, Witten's Gravitation: an introduction to current research or Poisson's a relativistic toolkit.
Leave MTW alone if you're not so patient in learning GR.
