All depends on the movie, the style you are going for.
Bourne shaky cam works awesome. But i can see why a select few won't like it at all. Slow Motion is another one that can work awesome, depending on the movie.
There's no "This technique sucks, period" truth. Long continuous shots ruled in Children of Men, but it doesn't mean they rule in other movies.
etc etc
Eagle Eye is an example of badly delivered shaky cam and quick edits.
