While very entertaining, the episode shows an egregious lack of understanding of the complexities of the IRA. Seriously? The IRA (which officially ended its armed campaign in 2005)wanting to bomb American sites? Really? Were they thinking RIRA, CIRA, INLA...,even then, it doesn't make sense. While one can enjoy the premise of the show, let's not be ignorant and stupid here producers and writers.
Plausibility is a real issue with this show, and it must be addressed by the producers. There is a great premise, kick-ass action scenes, and it is great to see a woman in such a strong role. The acting is very good, and the production is top notch. The stories need to be a bit more plausible though, even if they need to make up fake terrorist groups, rather than inserting known ones into an unrealistic situation.
