I went to the NYC Premiere and loved it. But I am a huge fan of the show and the film didn't stray much from the show. I was always on board with JLY as Frankie but not too sure about the other actors. By the end, I was sold on all of them! It was a little long (over 2 hours) but the time passed quickly for me.
It strayed way more from the show than I'd initially expected, but then I realized that was probably the best (or at least better) way to adapt this for film, since it wasn't going the cinecast route. It's a great film -- it just sometimes feels like a separate Four Seasons biopic that happened to cast a bunch of guys who were in Jersey Boys.
