This is closer to a 2.5, but that said, this story reeked of editorial interference. The original writing duo is ejected halfway this collection, and the disjointed melding of plot points really shows. This features the finale of Bart Allen as the 4th Flash before the title reverted to Wally (#3) for a handful more months. There are certainly some fun ideas here, it is fun seeing a Flash who has an alter ego as a cop again (er, or at least in the police academy), and the character's relocation to LA, is also an interesting change. This is all dumped quickly in the favor of *SPOILERS* killing the Flash.
Bart's death is handled pretty well, and is sort of heroic, but it rubbed me the wrong way how bloodthirsty the Rouges were, which was pretty out of character for them. The final issue in the collection is also pretty interesting, which features Wally's return to get revenge on Inertia, who was the main perpetrator of Bart's fate (also the eerie hunting down of the other Rouges which leads directly to Salvation Run). This is a mixed bag, but not nearly as bad as I thought it would be.
