Thomas the Tank Engine (Sharon Miller era and All Engines Go!)

' Thomas the Tank Engine' is an anthropomorphic train who is a major character in the British the titular protagonist of its TV series spin-off Thomas the Tank Engine and Friends''. During seasons 12 through 16, he has become badly butchered due to bad writing, especially in most Sharon Miller episodes. During seasons 13 - 16, he was voiced by Ben Small and Martin Sherman in the UK and US respectively.

Why He Sucked
NOTE: This will only focus on how he was butchered badly in Season 12-16.
 * 1) In "Splish, Splash, Splosh!", he was being very uncareful while playing in the mud, therefore, his wheels would've rusted. Which proves the point his mischievous in it's worst in that episode.
 * 2) He has lost all of the personality and charm he had in the prior seven seasons and didn't get it back until season 17. He was turned into an engine from being optimistic, kind, cheeky, fussy, smart, and playful to being so darn happy all the time, hardly pays any attention or even listens to what the Fat Controller says, and so on and on in those dreaded seasons.
 * 3) In Wonky Whistle, he had a strange whistle sound that sounded really ear-piercing to the point that it scared away all the animals from a wagon he was pulling to a fun fair.
 * 4) Overused a lot in seasons 13-16.
 * 5) Most of the episodes focused on him such as "Thomas and the Big Bang", "Wonky Whistle", "Percy the Snowman", "Up, Up, and Away", "Buzzy Bees", and so on and on prove that he is portrayed as an idiot, a clumsy simple minded character, and as well as an engine who screws everything up.
 * 6) Whenever there is a situation involved, he either makes things worse or messes it up until the things are set up right. Before flanderization, he had his moments when he would be careless and mess things up. But, in these seasons, he does it on a regular basis.
 * 7) In Misty Island Rescue he told Diesel he wasn't very useful because he was... well, a diesel. And he didn't get punished!
 * 8) He is basically a Thomas and Friends version of SpongeBob SquarePants in Seasons 6-8 of SpongeBob SquarePants.

Redeeming Qualities

 * 1) He was better in Seasons 1-11 and has redeemed himself since Season 17 and "Blue Mountain Mystery".
 * 2) There were episodes from the Miller era where he is in his best.
 * 3) He still cares about his friends and his branch line.
 * 4) Whenever he messes up, he does apologize and makes things right.
