I liked the movie not because of the Major plot of Noah and Elle but rather due to the development of Subplots...
Noah and Elle's story fails to give a fresh take on the sequel. I would have liked Lee's perspective to dominate the film; the Rachel & Lee dynamics could be continued where KB1 left off and give them a chance to shine. Rounded as they are, i think their story was the one that deserved the attention, alas we have another forgettable sequel for a great movie. Lee could have been more of a catalyst to Ollie's arch too!
