First of all, the good. The music was fairly good. If the actors did their own singing, they did a decent job. Also, once you got past the two leads, the actors were pretty good.
The bad was the dancing and connection between the main characters. Unlike the original, you see no emotion between them. The dancing was not even near the original in quality. While the backup dancers were very good, the leads reminded me of the week 4 participants on "Dancing With The Stars". Most of the dancing was shot around the dancing. Few full body dance steps were seen as most shots were upper body shots leaving us to wonder what their feet were doing.
I did like the idea that Baby was watching the stage version and reminiscing about that summer. The ending gave some closure to their future lives.
I have seen the original, the stage version and now the remake. The original is still far and away the best, the stage version a distant second and the remake not worth your time. Neither capture the character development and emotion of the original.
