Tommy could've looked like Tommy.
They should've hired an actor that AT LEAST somewhat resembled Tommy from the first movie. Nothing against the actor in this film. Teddy looked like he grew up to look as he did, but with Tommy it kind of shatters the illusion and distracts that some totally different black haired dude is playing the part. That was the only thing that bothered me.
That said, I really enjoyed this film and its definitely a worthy sequel to the first film. Funny and heartbreaking. Very heartbreaking. I can't believe I just now got around to watching it. Nice closure to a story that I loved. Goodbye characters :(
