I can’t think of anything in the last 30 years.
If we are using 30 years that gives us 1994 as the start date (which I'm okay with). I can come up with things on par with or worse than
The Acolyte with 1994 as the starting point (anything released after 1994 is fair game)
. The Phantom Menace for starters because aside from bits of the score, the movie is pretty awful. ("Duel of the Fates" is awesome but not enough to redeem the entire movie). I remember coming out of the theatre thinking, maybe the next will be better. I also had the same thought with
Attack of the Clones but for different reasons.
While the sequel trilogy was flawed, after watching
The Force Awakens, I thought the new trilogy was at least off to a decent start.
The Last Jedi was a giant narrative mess and
Rise of Skywalker doesn't follow logically after
The Last Jedi. It feels like there's a missing movie/story between the two that the filmmakers were aware of but the audience didn't see.
Book of Boba Fett was incredibly unfocused. It felt like a series of back-door pilots for other shows in the Star Wars franchise. It couldn't make up its mind what it wanted to be. Both series (
Book of Boba Fett and
The Acolyte) have the same issue of good idea, poor execution, but I think the execution of
The Acolyte was slightly better (but only by a little). There was at least a clear narrative through-line in
The Acolyte. It felt like
Book of Boba Fett became a completely different series halfway through the season (We now pause our regularly scheduled Boba Fett to bring you a two hour episode of
The Mandalorian). After that interlude,
Book of Boba Fett became almost a completely different show. That did not happen with
The Acolyte.
