Too drawn out, 90 minutes might've been perfect.
I like the idea of 'Into the Woods', with its mash-up of numerous fairy tales from 'Cinderella' to 'Little Red Riding Hood' to 'Jack and the Beanstalk' to 'Rapunzel'. I'd also say the musical pieces are enjoyable across the opening 20-30 minutes, which are nice and energetic.
However, from the midway point things start chugging down to a snail's pace. The novelty of the premise begins to wear thin, as it becomes clear that there isn't much more to tell - despite a load of the 125 minute run time still remaining. I will say, though, the look of the film is pleasant.
I do also rate the casting. James Corden seems to split opinion online, but I've always liked him; having watched and enjoyed him since his career took off with UK TV's 'Gavin & Stacey'. Emily Blunt and Johnny Depp are two of my favourite actors, while Meryl Streep and Anna Kendrick are strong casts. I like Chris Pine too, but he's iffy in this.
In conclusion, I almost found entertainment with this but overall it disappoints due to its poor pacing and gappy plot.
