FROM THE LONGBOX #4
After Batman bitch slapped three Martians in issue 3 Protex begins to lose his cool. Allowing time for Superman to think. He puts all the clues together and discovers their secret. Lighting Protex on fire with his heat vision, Superman escapes, and together with the rest of the JLA, they battle the White Martians knowing what they are up against.
So here Morrison brings our heroes together as a team, and he proves worthy enough to write them as such. Also he shows us how powerful Martians or even any shape changer can be. Ultimately, I thought the ending was pretty cheesy, but I find that there are a lot of great stories whose endings disappoint me.
In the end, it is a fine issue with a few stand out panels featuring Superman this time around. A decent if not perfect ending to a great story.
