It's because it stinks.
The acting stinks (Tim Omundson manages to be somewhat ok, but his character is empty and moronic).
The music stinks.
Woody Woodpecker's character and voicer is annoying, vapid, and obnoxious.
Everything and everyone is see through and one dimensional.
Universal was like,what's the crappiest thing we can do with a beloved character? Oh I know, let's butcher it with lazy writing and worse production.
Good grief it stinks.
