We loved Invasion! and so did the folks at SyFy Wire (formerly Blastr) as they listed Arrow’s 100th episode directed by James Bamford, as one of the best TV episodes of 2016.
“This hour walked the delicate tightrope of not only serving as a lynchpin in the “Invasion” mega-crossover, but as a celebration of the show that launched the Arrowverse. It did so in spectacular fashion. This was fan service of the best kind, with everything we would want to see: great cameos, high stakes and of course, awesomely choreographed fight scenes.”
