An imperfect movie in many regards, but just creative and energetic enough to make it a worthwhile watch in my opinion. Just be sure to keep your expectations going into it somewhat commensurate with the (certainly low) budget. At the core is an interesting story premise of four established thieves waking up captive in a fortified warehouse and being forced to plan and practice a diamond heist in order to stay alive. The writers take some story shortcuts that keep it from being as compelling as it could have been, and to me, were too eager to get to the backend/resolution of their tale, when the initial set-up and various unknowns are where the meat of the intrigue and interest truly reside. Still, there are enough twists and turns to keep the viewer engaged and/or guessing, and they deserve credit for that.
