i think we forget that untallented critics are the ones who are the consumers, and weather untalented or not they have to like something to part with their money.

Bingo. You are 100% right of course - it doesn't take artistic talent to like something, and having an opinion on the artwork on a pinball machine shouldn't get you criticised by self-proclaimed artistic experts.

Anyone want to say that artwork doesn't matter should buy themselves a Shadow and have good gameplay and they can also enjoy having Alex Baldwin looking down at them like he's just sucked a lemon or taken one for the team.
