Good, bad or in between?  Any recommendations?

It was good.  At the end Da Vinci executes janet reno in a trailer and feeds her to the hogs.

Excellent read.  If you are a religious FANATIC from the Catholic church, you may find it less than appealing, however.  But it's a great book.

I am a Catholic, but not an Opus Dei. I liked it.

It had a lot of interesting ideas and history.

I would recommend it and it is a fast read too.

It was tolerable, and I don't mean it was bad at all.  Twenty years ago I read "Holy Blood, Holy Grail" (which is given due recognition in "The Da Vinci Code") and I thought that the background story was far more interesting than the "mystery" of the novel.

Don't put too much credibility on the background story though.  What starts out as a great conspiracy idea begins to bog down (IMHO) when you run into characters who are fantastically wealthy individuals.  I believe this is a statement from the author that he really doesn't want to be all that creative, so he will introduce someone who can "realistically" supply any sort of plot device:  a private boat, a plane, fantastic soldiery, ninjas, spy networks, exotic equipment, a private bowling alley, large mansions, exploding Cuban cigars, death rays, Basque smugglers, Mossad assassins, sex toys illegal on three continents, all the green jello in the world, and/or Queen Elizabeth II.

Don't worry; the above list is not a spoiler and doesn't cover what you may find in the book.

"The Da Vinci Code" is a good read, but, as I said, the background is more interesting.
