Title:
Spectre_(2015_film)

Context:
Prior to its UK release, Spectre mostly received positive reviews. Mark Kermode, writing in The Guardian, gave the film four out of five stars, observing that the film did not live up to the standard set by Skyfall, but was able to tap into audience expectations. Writing in the same publication, Peter Bradshaw gave the film a full five stars, calling it "inventive, intelligent and complex", and singling out Craig's performance as the film's highlight. In another five star review, The Daily Telegraph's Robbie Collin described Spectre as "a swaggering show of confidence'", lauding it as "a feat of pure cinematic necromancy." In an otherwise positive, but overall less enthusiastic review, IGN's Chris Tilly considered Spectre "solid if unspectacular", and gave the film a 7.2 score (out of a possible 10), saying that "the film falls frustratingly short of greatness."
