The Love Guru is a retarded piece of garbage.  The only joke in the entire movie was the one played on anybody who watched it.  "Haha, suckers!"  
The Da Vinci Code was a pretty awful book, but could have been made into a really fun movie.  Unfortunately the poster-boy of mediocrity, Ron Howard, got his mitts on it.  At first I thought it might not be so bad.  Ron Howard basically paints by numbers while making movies, and The Da Vinci Code was pretty much made to be a movie -- a monkey could have turned out a decent movie based on that book.  But I totally overestimated his penchant for making unremarkable films.  The Da Vinci Code was remarkably bad.  I expected no less from Angels and Demons, but based on the reviews so far it appears he has outdone himself once again.
