The main character ruined it.
The mom/everyone else had good voice acting, the humor was natural, and the voices were pleasant to hear.
But the guy who did the voice for Ash was try way too hard.
He wasn't funny, didn't have good lines, used terrible insults/swearing, and basically sounded like a loser.
But besides that it was great, good graphics, smooth scene transitions, and overall and enjoyable movie.
It just needs a better male voice actor.
