Eh... They're too evil to be on the same level as Team Magma or Aqua, who are just a bunch of nuts summoning Leviathan and Behemoth for reasons that really weren't thought out well by either team and as a result really couldn't be taken seriously, too flat to be on the level of Team Galactic or Team Plasma, which both had good leaders with a lot of depth and really felt threatening, and too complex to be on the same level as Team Rocket, who are the Pokemon mafia, and don't need much depth because they didn't really HAVE any goals other than making money off Pokemon, and didn't really need any. They have the goal of completely killing everyone other than themselves, but really don't have a reason for that goal other than "oh, the world has too many people in it," and absolutely nobody treats Lysandre like a proper villain except for your party. Heck AZ had more depth than all of them combined, and actually had a believable reason for building a immortality-inducing death machine, and he's a very minor character that only appears a few times. Thus, I guess they're the Magikarp of evil Pokemon teams. Evil, but not threatening enough. Goofy, but too evil to laugh at. Too complex, yet not nearly complex enough.
