"All Crash would do is spin" is not a criticism, it's a selling point. The idea of a moveset that is all variants on spinning sounds amazing and the fact they wouldn't do that just kinda contributes to my indifference-at-best towards Crash in Smash.
It's still grossly understating what Crash's capable of, though. Also I can't help thinking people would accuse Sakurai of reducing Crash's entire moveset to "Him playing the first level of Crash 1 and making moveset from that", which I wouldn't blame them thinking. At best you'd have to add stomping on his kit to mix things up.
Sonic kinda ran on above for his moveset (even if due time constraints) and it's kinda ended making him feel dated more and more over the years.
I personally wish we got Crash in a new, better PSABR over Smash Bros (same for Spyro really), though.
@ Steve: I'm kinda ambivalent at him TBQH, he definitely needs good bit of work, but as someone from a franchise that has collab'd with Nintendo before and had the modern reach he does, he's fine.But after many other 3rd Parties, the novelty of him seems bit more of the same "big videogaming icon gets to Smash to smack Mario", making him feel less special on his own merits, and more a promo ad on Smash being the whole "Videogame Hall of Game", which I personally don't really feel being into, as it downplays other VG companies and their own possibilities to do something as celebrative of their legacy as Smash does.
Like, as of late it's been Astro Bot, which I also consider a swan song to Sony's overall legacy of it's Playstation-brand in all it's quirkiness and versatility before it's fully void of anything remotely unique in search for Western-based demographics and trends, whilst chasing AAAA-gaming fads that fall flat on their face.
... sorry about that, back on topic.
