I was a big fan of Thomas back in the day.
It had a few points of decline, the CGI as mentioned and when the endless introduction of new characters first started.
I struggled at the concept of the first tv series looking different to the illustrated books, Ringo Starr no longer narrating, Harold, Terence, Toby, Trevor and Bertie being introduced - but there are a million and one characters in it now and the theme tune has changed!
