Master Asbestos is right, these are dull! And a good paintjob would just make them well-painted, dull miniatures, nowt more.
As for the 'don't bash the sculptors until you've had a go' thing, well that's just rubbish. These are commercial sculpts. What is the point of releasing stuff if a vast majority of people don't like it or are indifferent to it? How will the sculptors/companies improve without getting decent crit?
I can't build cars, but it certainly doesn't stop me test driving them and complaining if they look shit.
If everything that was sold on this planet received a hearty reception with slaps on the back all round, we'd live in even more of a quagmire of mediocrity than we already do.
And mediocrity is a fate worse than death:D
