I watched that a few years ago (DVD from the library) and it was okay. Attila is grossly overrated IMO, and a few things in the movie were completely over the top not true. But it is entertaining, and due to filming in eastern Europe, there were large numbers of extras, and in battle scenes the extras are digitally multiplied.
I enjoyed seeing Powers Boothe in that production, he always gives a quality performance. He's done a lot of interesting roles over the years (for ex., Jim Jones).
