They're dreadful adaptations of the books, yes. But they're not "dreadful" on their own. There's really too much in each book to have been able to do better with those movies (they have said that they've separately considered making each book a two-part movie since Goblet of Fire). While it would be ideal to just read all the books instead, watching all of the movies will work fine if he just wants to see what it's all about.
