I'm giving it a "B", which is less than what I thought I'd be giving it given that (a) I am a pretty big fan of the Lego Movie, and (b) the 91% RT score, which usually tracks my opinion pretty well. On the positive side, it does capture much of the same verve, spirit, and humor that made the Lego Movie a winner. The wisecracks and asides hit 2/3 times, the lego characters are cute and appealing, and the animation-SFX are crackerjack. From a meta-perspective, IMO the mindless fun silliness of the Lego approach suits the Batman character better than the dark, brooding approach of Batman vs Superman, so this was a nice antidote to that. But ... even though the film is just 90 minutes long, it felt like a Looooooong 90 minutes to me. The pacing was poor, too frenetic for my liking. Whole plot twists and turns and action sequences would unfold and end, and ... just 10 minutes would have gone by. IMO, the makers just cram too much everything into the film, it's a case where less action, less plot movement, less everything, would have added up to 'more'. I'm 52 so maybe your sugar-addled eight-year-old will disagree, LOL. FWIW, a "B" is a decent grade to me, if I were on Siskel and Ebert it would translate into a "Thumbs Up". Just not as "up" as I thought it would be. One final thing: Of course this movie is going to be massive at the box office, but I got what amounted to a private showing. I saw an 11 AM matinee (2D) and was the only patron in the theater.
