More sluggish than entertaining, for me anyway.
I enjoyed the first film, but 'Maleficent: Mistress of Evil' is one I never really got into. The whole premise surrounding Angelina Jolie's character is uninteresting, not helped by a lack of serious rationale for why characters, other than Maleficent, are acting the way they are; namely Michelle Pfeiffer's Queen Ingrith. At best, it's lame motivation.
Jolie remains the star, while Elle Fanning is solid enough. Pfeiffer isn't as enjoyable as she should be, mainly due to the aforementioned, but still produces a good display. Chiwetel Ejiofor is a terrific addition to the cast, but I can't honestly say I'll remember his performance here - which is a shame.
Warwick Davis is, slightly, underused too. Also, how strange to see former professional footballer John Carew on the cast; albeit in a minor role. The effects are, pleasingly, an upgrade at least; they all look great.
I hold no ill feelings towards this, I just wish it was greater.
