Sing Street was cute but a little underwhelming. Granted I saw the third preview so hopefully they are still making changes, but it needs a lot of trimming. There are too many characters & storylines that go nowhere. They need to cut, tighten & focus. Also the show needs at least one BIG production number. Right now all the songs are staged very similarly. "Drive It like You Stole It" needs to have a wow moment.
But like I said, it's cute. I enjoyed myself but just wished it were a little better. I would recommend it if you can get a cheap-ish ticket. The songs are so good & it's fun to see them performed live. (They also added a couple new songs.)
