It's terrific to see Evolution back, especially with a specific mission, rather than simply reuniting to massage their vanities. It will be interesting to see how much Triple H intends to get physically involved; it's significant he didn't show up in wrestling gear when it was time to clean up the carnage wrought by the heels he sent to do their dirty work......which leads to another point: Triple H has certainly created an advantage for his team that most groups don't have....yes, he, Orton & Batista can beat up their foes, but Trips can also use executive privilege to "legislate" Evolution's path through their enemies, either by physical or political means.
Also, even though the Shield are now fighting on the side of truth, justice & the American way, it's kind of exciting to see the tactics they brought against others used to thwart them now. They were the heels that ganged up on others to make sure one of them wasn't defeated; last night the tables were turned by a team that possessed a numerical advantage over them. Sure, we root for Shield now, but it's not as if their reign of terror never happened.
To that end, Evolution....plus the powers they command outside the three of them.....has proven itself to be a formidable force, one that has already taken the measure of the Shield. Gonna be interesting to see how this proceeds.
