The cast was great and the cinematography was good, but I hated two major things about it. First, the British actors speeking with their British accents, it felt a lot more like a documentary reenactment and didn't put the viewer in an authentic atmosphere (I can't imagine Ukranians speeking with a perfect British accent). Second, the main explosion and meltdown scenes were supposed to be spectacular, they looked like a low budget production work. The potential was high and my expectations were even higher, but i was disappointed after watching it.
