OP's question was about technical side, so there's no thing like "oveproduced and bland". In case of IM I also think all this flashy techniques are there not to make impression, but to really help tell the story better and in more tangible way - listen to Milosh from last album for example: the main motiff is incredibly emotional, but its impact is doubled (or tripled) by the way it's delivered. Technical prowess for IM is just a tool, whereas for a lot of other artists it's where their knowledge ends: they'll obsess about kick or bass sound (I read today a post from guy layering 7 kicks on top of eachother and still not getting it "right"...) writing pristinely sounding ...crap. We may not like IM's output especially because for years it's not goa/psytrance anymore, but objectively their music has a lot of soul, magic and individuality and immaculate production only helps fleshing that out.
