^ If the Duck Hunt is actually good and utilize his reat pressure and trap options then yeah. If he does little but sit there camping almost the entire time, then not really. As far as I've seen, most Duck Hunts are kinda bad and do just that, and given his absurd learning curve I feel that there aren't too many people who use him even close to his full potential. Actually, considering how he isn't that popular, its kinda hard to even find people playing him at all. In general, aggressiveness in Fighting games is usually considered more fun to play and specactor than defensive play (which is why Melee is a lot more popular than Brawl competitively). Although he's obviously not a rushdown character, I think Duck Hunt is super good at playing offensively due to his high damage, great approaches, and pressure options with his projectiles; I even go as far to find him better find him a little more effective as an offensive character than a defensive one who plays with careful aggression, considering how slow and awkward his projectiles are.
With all this, I think Duck Hunt has potential to easily be a crowd pleaser. The trouble is, he doesn't really have enough players to attract enough spectators and isn't really that popular as a whole character in this game. And as for the few who do play him, I feel most of them just sit there camping and don't really utilize the other cool stuff he can do, and it seems to me that its kinda making him look bad since not everyone enjoys highly defensive play.
To sum it up, I think he would and could appeal to crowds, he just doesn't have enough players that show what he's made of.
