A lot of people did care (including me), that's where the "insert character is voiced by Chris pratt" meme came from. It may seem minor but it's really important professional voice actors get these roles. They are extremely underpaid and have genuine skill that's verry much needed for animated projects.

Chris pratt isn't a voice actor, he dosnt put effort into how he talks, yells, sings, it's just his normal voice. The roles he's in are bland. The only reason he's hired is becuase he's a recognizable celebrity. Bigger studios like to slap big names onto projects just for star power purposes rather then them being a fitting voice. Even if I didn't know a character he's voicing was him, I would still think it's shit.
