It's only now he enter the uber highly polish area of gaming. Before I would say he was Tarantino lite. Tarantino get everything right, suda is (was) not at that level yet.
I disagree with both this and what mooosh said. Flower Sun And Rain is very much in the same style as Killer7 and No More Heroes, the only difference is that it's a lot less violent. Admittedly, I haven't played any of Suda's games older than that (haven't played Michigan either), but The Silver Case also looks similar.
If we're going to compare Suda to Tarantino, I'd break his ludography(??) down like this:
Flower Sun And Rain = Reservoir Dogs
Low budget, small scale but already shows his distinctive style.
Killer7 = Pulp Fiction
The point where things really start coming togehter for him. He finally manages to turn his "good ideas" into an actually great game (with Mikami's help though).
No More Heroes = Kill Bill (also note that it's the only Suda game with a direct sequel)*
Same basic ingredients as Killer7, but mixed together in a different way, resulting in a game that's "lighter" and more about mindless fun.
Shadows of the Damned = Inglourious Basterds? idk
*Come to think, FSR was a sequel to the Silver Case (or at least that's what I read), so nvm.
