Tommy is not a bad show, I just have not yet seen a good production of it. Also, Tommy is not original. The show is the stage adaptation of the 1969 album. To say Tommy is original is like saying American Idiot is original when it was also an album prior to being a show ( funny fact, both shows were albums prior to being on Broadway and both shows shared the same Broadway house, The St. James.)
In fact, after Townshed won the Tony for best score, the Tony Committee altered the rule to be nominated. The new rule was that a show had to have fifty percent of its score written for the stage. Townshend won a Tony for writing songs that he wrote in the 60's so nothing was written for the stage ( with the exception of I Believe My Own Eyes and Sally Simpson's Question...but still.)
