Pros
-Good interactions betwern the Trinity
-Phil Jiminez was the perfect artist for this story, and every page he draws feels epic.
-Alexander Luthor jr. is a great, multifaceted villain and should've been in Superboy Primes place to have a future beyond IC
-The scene where Batman almost kills Alexander Luthor jr. before being stopped by Wonder Woman is great
-The times were Hal Jordan appears in IC are very well done and there is a great scene of Hal saving Batman which calls back to Batman's mistrust of Hal in GL Rebirth
-Dick Grayson is portrayed as being on par with the Trinity.

Cons
-IC is so fast paced that there is hardly time to dedicate focus on things such as character development. For a 7 issue series, there is no room to breathe.
-Batman is responsible for the deaths of millions of people due to the Omac project. I would make the argument that the character assassination for Batman is worse than it is for Wonder Woman
-Deathstroke is inconsistently written. Is he a merciless killer or a villain with a code?
-Superboy Prime. Is there a worse villain in comics?
-Jarring fill in artists lessening the impact of the story. Reis, Perez, Ordway, and Bennet are all good artists, but their presence makes IC incohesive.
-The subplots involving the Secret Society of Supervillains, Omac, the Spectre, and the War between Raan and Thangaar are irrelevant in the grand scheme of things. The only plot thread that matters is the creation of the Multiverse
-The multiverse is completely uninteresting.
-I kinda liked Power Girl as an Atlantean. . .
-Booster Gold and Jaime Reyes are the only non Trinity/Superman family characters with an arc who appear throughout IC. This should have probably been done in a tie in, because they have almost no bearing on the main plot.
