Maybe it doesn't have that actual thriller elements of the original, but that's completely reasonable. Once you see Chucky go full force for the first time, it's pretty hard to try and reel him back in to a "Is he or isn't he" mystery for the sequels. And even if it is a step down from the first Child's Play, getting to watch new characters experience their "I was so wrong I died" moments is always a cause for glee.
Final rating:★★★ - I liked it. Would personally recommend you give it a go.
