Unfortunately they deserve the bad reviews.
However the iWork for Maverick Apps are free, if you had them previously, and you can make your own assessment.
Just make sure you protect existing documents, with back ups as the new file format is so different they will be altered/damaged when opened in the new Apps.
There a few new features and touches to Pages 5 but they are completely overwhelmed by the removal of over 90 features, bugs and bad UI:

Even given the new features, most don't really work, or just work badly. The T.O.C screws up, the Right to Left text is faulty and the best of the new features, Object Styles, is not as solid as it should be. Drawing is better but still not up to the standard of a full on drawing program.
