I don't see a problem with Crabbe and Goyle (or Goyle and Blaise Zabini) destroying one of the horcruxes either.
That's a problem some people had with the book as well. If you look at the list of people who destroy the horcruxes, you have:
Voldemort himself
Dumbledore
Ron
Hermione
Harry
Neville
...and Crabbe.
Like, I don't see the problem with it, but I do think it's funny.
To be fair, in the book I didn't like how Fiendfyre was one of the few things that could destroy a Horcrux (and it wasn't even mentioned at all at the start of the book) and Crabbe just so happened to cast it.
