ITV Grace: Is It Bad Acting or Bad Script Writing That Ruins the Show?

by Chris Harris

There’s a moment, watching ITV’s Grace, when you begin to question your own judgement. Something feels off. The dialogue doesn’t quite land, the emotional beats seem muted, and even John Simm, an actor of proven depth and presence, appears unusually subdued. It creates an uncomfortable suspicion: is the acting actually… not very good?

But that instinct doesn’t quite hold up under scrutiny. Because Simm hasn’t suddenly lost his ability, and the wider cast are far from inexperienced. What you’re sensing is real, but the explanation lies elsewhere.

I like whodunnits, but Grace is poor. I continue to watch because it is set down the road in Brighton, home of my misspent youth and occasionally in Lewes, where I live.

The Illusion of Bad Acting

At first glance, Grace does appear to suffer from weak performances. Almost like Hove Drama School has been raided. Conversations can feel stiff, as though characters are reciting rather than speaking. There is that millisecond where the actor looks wooden, like an Argentinian soap, where at the end of the sentence they seem to be reaching for something to complete the dialogue. So emotional scenes sometimes pass without impact, and supporting roles occasionally drift into a kind of polite flatness. It’s easy, in those moments, to blame the actors.

Yet this is misleading. What looks like poor acting is often the result of actors working within tight constraints. When dialogue lacks rhythm or authenticity, even strong performers can seem unnatural. They are left trying to animate lines that don’t quite breathe, and the result is a kind of restrained, careful delivery that can be mistaken for lack of ability.

The Weight of the Writing

The deeper issue lies in the writing. Grace frequently relies on functional dialogue that exists to move the plot forward rather than reveal character. Conversations explain rather than explore, and emotional moments are stated rather than built. This creates a subtle but persistent distance between the audience and the characters.

Compounding this is a lack of tonal clarity. The show shifts uneasily between dark psychological drama and conventional procedural storytelling, never fully committing to either. That uncertainty filters through every scene. Actors are left navigating unclear emotional territory, unsure whether to lean into intensity or restraint, and so performances settle into a cautious middle ground.

Even the central character suffers. Roy Grace is written as quiet and haunted, but too often this translates into a kind of narrative emptiness. Without sharper definition or richer inner life, the role offers fewer opportunities for an actor to fully inhabit it.

Why the Show Never Quite Comes Alive

What emerges is not a failure of talent, but a failure of ignition. The cast of Grace is more than capable, yet the material rarely gives them the chance to elevate the drama. Instead, performances are flattened by dialogue that lacks spontaneity and by storytelling that prioritises structure over depth.

This is part of a broader pattern in mainstream ITV drama, where reliability often takes precedence over risk. The result is television that is consistently watchable but seldom memorable. Compared to more character-driven dramas, Grace feels controlled rather than lived-in, competent rather than compelling.

In the end, the problem isn’t that the acting is bad. It’s that it never quite has the space to be truly good.
