snipped a massive amount.
Personally, I think GoF wasn't really very sloppy.  The thing is 700+ 
pages and intricately plotted.  A few minor glitches got through 
(e.g. the number of times Harry was under the Imperius curse).  All 
of those are forgivable, and are things most readers wouldn't catch 
on a first read, and therefore don't impair the enjoyment of the book.

The emperius thing was not a mistake.  True, Harry hasn't been under the
emperius curse three times; he's only been under it twice.  But if you
remember, at the Quidditch world cup, when the Veela started dancing,
Harry's mind "went completely and blissfully blank", just as it seems to
when he is under the emperius curse.  JKR doesn't specify where the
other two time s come from, you're just expected to know that he's felt
that way three times.
