^It's not lazy, that sentence is true. It happens in every creative field. It's unfair, but life in general is unfair and people have to deal with that. Miuccia certainly has managed to create hype around her brand and build a particular world, but that doesn't mean everything she does is great.
The quality of a collection is not something subjective. You can like or not, but that doesn't mean this is good, new, original or whatever, which is not. Sometimes I feel 'attracted' to bad collections, but that doesn't make them good. It's easy to differentiate when something is good, bad, new, demodé, original, lazy or whatever. This is lazy and quite boring in every level, not matter the amount of trinket and colors involved...
The best Lang collection would be considered good if it were done by an unknown designer. If this were done by someone else... no one would care about it.
