It’s probably cheaper to produce tv series that are going to pack the Disney streaming channel content with events such as the Ben show. For them it’s a fair deal, and currrent audiences are getting used to this “movie to tv series” trend. Disney has produced 5 SW flicks for Theathers, among them only 2 got smooth productions (TFA as it was triggering some excitement, TLJ being done a bit under the radar), while 3 went to hell (R1 and its heavy reshots, Solo being reshaped with late change of directors, TROS which looks like something no one wanted to do). Issue is that the tv series themselves are now quite lackluster (Mando got its moments but Boba was a mess, Ben was a failure, Bad batch was mostly fillers driven, ad most of TCW S7 was very bad until the ROTS very good side story).
