It's your standard All Stars movie. I immensely enjoyed the combat scenes. I'm glad that some of the older Cures got speaking lines since in New Stage 1 they didn't talk at all. It was a good introduction to the Happiness Charge gals.
The 3d ending was very pleasing to the eye too. My only real issue was pacing. It was just "Precure defeat monster, monster powers up, repeat" until we got past the 1 hour mark. The Nightmares were also very funny looking and I couldn't really take them seriously at all. In the DX installments, the villains were actually scary with Fusion, Bottom and Black Hole.
These were just raging neon teddy bears. But, overall, very fun movie.
