I have not seen Les Miserables, but have heard the criticism of Crowe's performance. I disagree with your stance. The guy sings more than just a bit and has done so throughout his career in entertainment. He probably has done as much if not more singing during his career than either Jackman or Hathaway. All three have sung in musical productions before, but I don't recall Jackman or Hathway being members of any band like Crowe is. Whether Crowe's singing is good or not is another question, but singing has been a significant part of his life.
