I personally liked it a lot (although I don't think it's "great" either), because I find it very funny to see cartoon characters in roles that are far from their canon. I've even found moving the scene where Wiley shows the value of persistence.

The Looney Toons Show from 2011 - I thought the same about role changes, but the show is an absolute gem, at least the second season when they got the characters to gel.
