Not only is Decade one of the worst Rider shows ever, it's probably one of the worst tokus of all time.
Barely a plot (and an incoherent one when it did exist), no direction, absolutely dreadful characters that barely get any development, and Toei thinking the audience is so stupid that it can throw in a giant heap of meaningless fanservice (is it really fanservice if I'm not serviced?) and get away with such shoddiness. Though with all the lavish praise this junkpile has been getting, I guess you can't fault their strategy >>
This proves Toei can't do anniversary shows, or have lost the ability. From now on they should either defer all anniversary Sentais and Riders to Tsuburaya, or hire Tsuburaya writers experienced with Ultra shows. (Though that may not work either, with Bandai having such a long arm as it does.) I have little optimism for Toei's future shows, including W.
