Now that is the Crisis
11 December 2019 | by rohithdrplSee all my reviews

Should have been like this from the beginning. Lucifer Morningstar even for 2 minutes was a great addition. Arrow's story ended oddly or is it ? If Arrow doesn't return in Part 3 or Part 4 in that case major part of this episode doesn't even make sense.
