Thomas is just ugly in general; now before any of you jump down my smokestack, allow me to explain myself. The TV Character version of Thomas, at least, is ugly, as far as I'm concerned. Rev. Awdry did a fantastic job of sticking to the original proportions of the locos he based his characters on (thomas being an LB&SC class E2, Percy being a Peckett 0-4-0, Henry's a 'Black 5' 5MT 4-6-0, etc.) the fact the TV morons ruined such classic, graceful lines of british steam power by misshapennly cramming their shells onto Marklin mechanisms is appauling.
oh, and @pfx, ditto on your gripe...
The original series was in my opinion the best. George Carlin was the best narrator they had. And I thought Thomas was an 0-6-0 Terrier.....oh well, learn something new every day.
