Shaggy Rogers (S&SDGAC, and BC, SD!)

Norville "Shaggy" Rogers is a fictional character in the Scooby-Doo franchise. He’s normally a likable character in the franchise. Unfortunately, in Shaggy & Scooby-Doo Get a Clue!, this Shaggy was badly flanderized and became horrendously out of character.

Why He Can't Get A Clue
NOTE: This article only applies to the character as depicted in Shaggy & Scooby-Doo Get a Clue!
 * 1) In this show, he is horrendously out of character when compared to his previous incarnations of the series (perhaps even more so than his Be Cool, Scooby-Doo counterpart), as he went from a cowardly, helpful, likable, energetic and actually funny comic relief into an extremely lazy, unlikable and generically unfunny comic relief for no real reason.
 * 2) He is part of the show’s misleading title, as he (and Scooby) DOES NOT get a clue whatsoever in the show.
 * 3) His laziness has become obnoxious, annoying and troublesome, which is unlike his usual self, in which he’s only occasionally lazy.
 * 4) He contributed to the show’s poor grasp of source material:
 * 5) * In this show, he doesn’t eat the Scooby Snacks with Scooby. Only Scooby does it, because the snacks are portrayed as generic power-ups for Scooby, for some unknown and weird reason.
 * 6) * He also contributed to the show’s more lighthearted tone when compared to the spooky atmosphere that previous (and later) incarnations had (and yes, that includes Be Cool, Scooby-Doo!), which does not fit Shaggy at all, thus he doesn't even feel like a Scooby-Doo character and feels more like a generic kids cartoon character released in the 2000s.
 * 7) With regards to the art style, his character design looks really weird and a little uncanny. It's interesting to note that he's supposed to represent his live-action appearance from the live-action Scooby-Doo movies.
 * 8) His humor and jokes have become very poor, even for Scooby-Doo standards, only relying on fart jokes and toilet humor.
 * 9) He’s part of the extremely confusing intro. It shows him running out of nowhere back and forth in silhouettes, and he’s also doing weird dances (with him coming off as either he’s typing in mid-air or he’s doing air piano, as Mr. Enter pointed out in one of his videos).
 * 10) He’s part of the stupid premise, as there is no way he and Scooby became rich.
 * 11) He has a poor and annoying voice, lacking the genuine charm the character’s voice normally has (from Casey Kasem, Matthew Lillard, and Billy West, who voice him a lot better), and it doesn't help that Scott Menville voices him, and he’s normally a great voice actor, but his voice as Shaggy is bad, wimpy, and sounds way too high-pitched and squeaky for the character.

Redeeming Qualities

 * 1) He was a much more likable character in all other entries outside Shaggy & Scooby-Doo Get a Clue (and Be Cool, Scooby-Doo).
 * 2) He still has some genuinely funny moments.
 * 3) It is nice to see an incarnation of the series solely focused on both him and Scooby, even if it wasn't executed very well.
 * 4) "Uncle Albert Alert" is the only episode of the series where he’s likable.
 * 5) He thankfully improved in Scooby-Doo! Mystery Incorporated, because the writers not only made him not lazy anymore and go back to being his normal, energetic and funny self, but they also gave him more character depth to make him feel more like a fleshed-out three-dimensional character. Also, this was Matthew Lillard‘s TV show debut as Shaggy, and he has since voiced Shaggy amazingly (yes, that includes Be Cool, Scooby-Doo).
