Mass Effect 2 - Lair of the Shadowbroker Reviews

Looks like Lair of the Shadowbroker is getting good press, with a couple of positive reviews.  In fact, IGN goes for a massive 9.5/10 in their critique:

Clocking in around three hours, Lair of the Shadow Broker unravels the engaging tale at a great pace. Despite the dark themes of murder and betrayal, the conversation can be quite humorous. There are some really great moments between Shepard and Liara, and the storytelling effectively communicates the strong bond between the two, even if they weren't romantically involved in your game. Over the course of the story, it's clear that Liara has evolved from the shy girl Shepard met on Therum into a hardened woman struggling with her feelings of loss and guilt. To keep everything balanced, BioWare tossed in some self-deprecating material, including jabs about the Mako's wonky controls and using Omni-gel to open any door. Visually, Lair of the Shadow Broker boasts some really breathtaking environments. The cut-scenes are beautifully rendered and approaching the Shadow Broker's ship is simply stunning as lightning storms envelope the massive vessel.

Joystiq doesn't use scores but it's clear they like it:

There's a lot of well-polished content here, with some of the more beautiful vistas in the ME universe. However, it's over too soon. Even if you watch all the videos, unlock all the terminals, and read all of the Shadow Broker intel available to you (It's required reading: these vignettes offer hilarious insight into all the major characters in the game), you're looking at only two hours of gameplay. At 800 Microsoft Points ($10), that's a hefty price to pay, especially compared to the retail game's hour-to-dollar ratio.

Considering the importance the Shadow Broker plays in the Mass Effect universe, it seems odd that BioWare would conclude the story in DLC instead of Mass Effect 3 as skipping this DLC will put players at a narrative disadvantage. This isn't a compelling (but ultimately disposable) side-story -- Shadow Broker is a must for any Mass Effect fan, casual and hardcore. It feels like BioWare and EA, fully aware of its importance, have taken this crucial arc hostage as DLC, and have bet that you're willing to pay the $10 ransom.
