does he really have to direct every Harry Potter related film now?
He's essentially the John Glen of the Harry Potter series. Competent and reliable enough to turn in a watchable film, but largely lacking in vision and creativity.
Despite the massive budgets he gets, his films always end up just feeling like well-produced TV movies, with no sense of scale or grandness present. The best example of this is with the second Deathly Hallows, where Yates took what was supposed be an epic, action-packed, showstopping finale to the Harry Potter series and turned it into just another adventure revolving around Harry, Ron, and Hermione, with little of the fireworks needed to make it feel like the biggest of the lot.
His approach to storytelling always feels as though he's still working from the same mindset he had while working on television, that of swift narrative pacing, efficiency, and minimal spectacle to counteract the micro-sized budgets and limited runtime allowance. Difference is, Harry Potter isn't some low-budget BBC production that is only allowed to go up to 90 minutes max. He has all the resources in the world to help him tell the story in the exact way it needs to be told and yet, he always opts for the driest, most unimpressive style imaginable.
The guy's done seven of these films now. Can we please get someone else?
