List the 5 series (tv, book, or movies) that best kept their quality, from beginning to end.
This is a subject incredibly close to my heart. There is nothing I hate more than a show that I adore which the writers ruin through characterization or pacing fail. More shows have done that to me than I have fingers, frankly. (The reason it's so common, imho, is that the US television system is set up so that shows become most profitable once they reach 100 episodes and go into syndication, which results in shows that only have a 13 episode or 22 episode or 44 episode story being dragged out).
So, five shows that have kept there awesome all the way through or remained as good as they started are:
–Burn Notice. Three seasons in, and it's still awesome. Cross your fingers tomorrow's premier doesn't make me eat my words.
– (excluding the movie) Firefly.
–Legend of the Seeker. Cancelled before it could break my heart.
–(the original) Fullmetal Alchemist anime. Haters to the left.
–Princess Tutu
(Notice how two of these shows were cancelled and two are Japanese? Because I certainly did.)
