The only show anyone should apologize for loving is Cats.
Having said that, Les Miz can be a little boring at some points (especially if the cast is not as passionate as the characters they're performing) but when it soars, it really soars. I love the score, Frances Ruffelle's "On My Own" is simply mind-blowing, and One Day More is one of the most energetic Act I finales.
