This review is very bad in many terms.
First off, it starts by saying JoomlaWorks is bad on their support forum (?) giving the assumption to other users that both the paid extensions and K2 are on the same forum, which is completely false. K2 is on a separate domain and forum for the record. If you wish to critisize other extensions, you can do so elsewhere. It's like leaving a review on Virtuemart and saying AllVideos is to blame (?)...
Secondly, this statement is pretty low "Joomlaworks has to be one of the worst in the community for support". You do not reference a single link where the support was bad. So you basically accuse JW without at least providing any pointers.
Thirdly, where is the constructive criticism? "K2 re-invents the joomla content wheel"? I'm devastated by that, really...
Fourth, this is a review from a user called "WTF brb". I rest my case.
I thought the JED allowed constructive criticism and not reviews that just say "this is bad, you're horrible" and that's it. Is it bad? Explain why. If haven't spent enough time with K2 or any other extension, devote more, then provide a review.
My own wish is to stop it from interfering with the Google Maps plugin.
