Fans of “Gone Girl” who have been patiently waiting for star Rosamund Pike to sink her teeth into another delectably devious role, rejoice. J Blakeson’s “I Care a Lot” provides the best showcase of Pike’s darkly ambitious drive since her Academy Award-winning breakthrough in 2014. None of this is intended as a slight to her work in the interim, to be clear. But there’s just something joyous in seeing that devilish twinkle return to Pike’s eye as she charges forward to fulfill her objectives, regardless of the pain it causes others or the lies she must tell along the way. She’s the key component in the project pulling off the increasingly rare balancing of visceral entertainment and intellectual stimulation within the adult dramatic thriller.
