...and did that continue to influence your preferences with regards to the franchise?
I was first introduced to the X-men through X-men Evolution in the early 2000's, and I do think that show continues to shape a lot of my X-men preferences - the school, teenage mutants struggling with their newfound powers and training to become superheroes, the X-men trying to retain some measure of anonymity and operating below the radar etc.
Wolverine didn't hog the limelight in Evolution, and consequently I've never been that obsessed with Wolverine's role on the team. I consider myself an X-men fan first and a Wolverine fan second, and I'd say that Hugh Jackman is the major reason why I'm a Wolverine fan at all!
Conversely, Cyclops has always been a favorite of mine because of Evolution. He seemed like a cool, but mature, guy, the sort of high-schooler I wished to grow up to become. And as a kid, I was very invested in the slow-burn Scott-Jean romance on the show.
Incidentially, it took me ages to even stomach the idea of the Scott-Jean-Logan 'love triangle' The Jean-Logan romance has never made sense to me beyond some mild flirtation, and Evolution wisely refrained from going there given that Jean was a teenager. (Incidentially, the one time it made sense to me was Ultimate X-men, where everyone is generally a lot more messed up and its depicted as an illicit affair).
Anyway, the Evolution team remains the go-to lineup for the X-men in my head, with a few additions like Colossus and Iceman (both of whom join the team in the flashforwards of the series finale). I love the TAS line-up and it is truly iconic, but deep down I'd take Shadowcat and Nightcrawler over Jubilee and Gambit.
I also liked the show's depiction of Magneto, at least early on, as this more enigmatic, mysterious and powerful manipulator. The show's Mystique is another favorite of mine. And this is probably the best (or at least the most fun) depiction of the Brotherhood. Lastly, I thought the Acoyltes were cool as **** when they showed up!
After Evolution, I guess my next big touch-point was the early Ultimate X-men arcs, as well as the Fox movies. I read some of the then-contemporary comics from the Morrison era which felt pretty jarring and totally different from any other X-men stuff I'd been reading around that time (specifically I read the issues where Archangel loses the blue skin after an encounter with Black Tom, and begins his affair with Husk). And of course, I started catching reruns of the TAS, which really opened my mind to the wider X-men mythos, especially stuff like Bishop, Cable, Mr. Sinister, and the Shiar. I also read some issues of X-men: The Hidden Years around that time, which felt familiar because it had teenage X-men, but also jarring because the O5 era was completely different from how I imagined the early days of the X-men after watching Evolution and reading Ultimate X-men!
