The Metal Virus has been defeated, but Sonic is nowhere to be seen! Doctor Eggman takes this as a prime opportunity to attack, but just because Sonic is gone doesn't mean the world is without protectors. Plus, untold tales of the Metal Virus saga!
This volume is basically the epilogue to the Metal Virus, as well as Ian Flynn's run on the book. While Sonic's fate is a forgone conclusion (this is a Sonic comic after all), the more interesting things are happening to the people left behind. It's often Sonic's supporting cast that are more interesting than the Blue Blur himself, and this is a good example of why, since they're great when they get to take centre stage. I always enjoy Amy getting some spotlight time, for example.
The annual feels a little out of place; it'd really have been better collected during the Metal Virus Saga itself, but that would have overloaded one of the trades so I guess that's why it's here instead to fill out space. Most of the stories are decent, although the Big The Cat one really stands out as he does his usual thing of wandering through the events of the story to find Froggy as hilarity (and heartbreak) ensues.
I doubt I'll comment much on the art any more. The rotating team of Sonic artists are all very similar in tone given the subject matter, and unless someone stands out or falls flat, I'll just say that it does the job and move on.
Out Of The Blue isn't a bad volume at all, but it does feel a bit tacked together and tacked on. The character work is solid, but the story is mostly just a reset/return to the status quo, which is to be expected, but still a little disappointing. I hope that Sega give IDW a bit more creative control like Hasbro have with TMNT and Transformers, so we can get something a bit more substantial in the future.
