The Prequels have huge flaws that make the first two basically pointless.

Obi-Wan is sidelined in TPM and all the story beats he should have had were shifted to Qui-Gon.
Hayden wasn’t able to develop his character through three movies because having a nine year old Anakin was important for some reason. We don’t want to see little kid versions of OT characters (Boba Fett), this is some Pup Named Scooby Doo crap.
The AOTC plot is stupid. The Sifo Dias stuff is dumb. Obi-Wan knows the clones were based off Jango Fett and sees Jango Fett go to Count Dooku yet they still use the Clone Army without any questions.
Hayden and Natalie have no chemistry.
Christopher Lee is wasted.

Also I’m sorry but General Grievous is dumb. Should have been Maul with cyber-legs. Imagine the duel from Rebels after Obi-Wan chases Maul through Utapau. Would have been an epic scene that ranks up with Yoda lifting the X-Wing. But no, more flippy duels and overlong lightsaber fights.
