“Camera-shy Australian Sia occupies a singular position as a hit pop songwriter who moonlights as a chart-topping artist in her own right. ‘This Is Acting’ features tracks she wrote for A-listers including Adele, Beyoncé and Rihanna but kept for herself after they were rejected. It’s an album filled with scraps, then – but they’re scraps that would be snapped up by most pop stars in a second. Any ”
“Some of the tracks, like the first few ballads, feel a tad exhausted and perhaps a little clichéd, but that's the nature of Sia's universal, inclusive pop music, and on This is Acting, she approaches it in an intriguing way and performs it with gusto.”
“In a few short years, Sia has gone from subverting the mainstream to being the mainstream. In light of that transformation, you'd expect more than an almost play-by-play recreation of her most recent highlights. Her new album This Is Acting can't help but feel like the big-budget sequel to 1000 Forms of Fear's sleeper-hit success.”
“The album maintains a competent level of craft but lacks a big hit to pull it together”
