Dr. John Deegan: My name is John Deegan, and I'm from Gotham, a city in grave need of heroes. As a doctor at Arkham Asylum, I did my part by protecting this city from the criminially insane. The world didn't understand my methods, so I worked in secret until, one day, when a cosmic being recognized my potential and gave me the chance to be something greater. Someone greater.

Good Ending
13 December 2018 | by Mohammed_NabilSee all my reviews

This is the last episode of the crossover. The acting was really good especially the lead actors. The villain was really interesting and I really enjoyed LaMonica Garrett's acting as The Monitor. I really liked the dynamic between the heroes and the villain. The humour and emotions was really good. There was actually good lessons to be learnt in this episode. The unfolding of the story was done pretty well.But there were many inconsistency and issues in this episode. The ending was really good. The after credit was the thing that made me the most excepted.
