Task: Question Answering
Input (English): Passage: 4 received positive reviews from music critics. At Metacritic, which assigns a weighted mean rating out of 100 to reviews from mainstream critics, the album received an average score of 73, based on 36 reviews. Michael Cragg of The Observer called it Beyoncé's "most accomplished album yet". Slant Magazine's Eric Henderson believed 4 succeeds vocally as an album of mostly intimate and slow-tempo ballads. Mikael Wood of Spin magazine applauded its ballads, mid-tempo songs, and evocations of late 1970s and early 1980s pop-soul. In his review for Rolling Stone, Jody Rosen wrote that Beyoncé eschews contemporary production styles for a more personal and idiosyncratic album. Jon Caramanica of The New York Times viewed it as a good showcase for Beyoncé as a torch singer, because she convincingly sings about heartbreak and the strong emotional effect of love. Pitchfork critic Ryan Dombal found it easygoing, retro-informed, and engaging because it shows "one of the world's biggest stars exploring her talent in ways few could've predicted". AllMusic's Andy Kellman said that the quality of Beyoncé's singing and the songwriting compensate for the assorted arrangement of the songs. Uncut viewed it is an exceptional album in spite of occasionally trite lyrics.In a less enthusiastic review, Adam Markovitz of Entertainment Weekly said the first half of 4 is marred by boring ballads and the songwriting in general are not on-par with Beyoncé's vocal talent. In his review for The Guardian, Alexis Petridis was ambivalent towards the album's 1980s influence and argued that, despite well written songs, it is not very consequential. Time magazine's Claire Suddath said the songs lack lyrical substance, even though they are performed well. Greg Kot, writing in the Chicago Tribune, called 4 inconsistent, short, and unfinished. NME magazine's Hamish MacBain felt Beyoncé did not progress from her past work and that "even the OK bits here" sounded "uninspired". 
Question: What is the full name of the critic who said the album with 36 metacritic reviews was not very consequential??
