I thought of it as more of a parody, almost; things that were major plot points only because they were hidden from the reader are presented up front (Harry's invisibility cloak being special, or the time turner, or the DADA instructor curse) which makes them be pretty pointless to any actual plot. This makes them funny. Beyond that (and of course Harry being, well, a nerd) it's not awful for canon. Sure, there's a bit more over the top characterization (Dumbledore gets hit really hard by this, and the kids only act 11 when convenient) but that's not really canon-related. I guess there's probably a bit much "Ender's Game at Hogwarts", though.
