Nekrotronic is “fun,” but often in an off-putting, aggressive way. The Roache-Turners have prioritized fleeting moments of gross-out humor and special-effects dazzle over a controlled pace, or careful world-building.
The fact that none of this usually-surefire mindless stimulus is remotely inspired — let alone that the plot feels like a barely-there afterthought — turns so much cheerful sound and fury into near-senseless din.
