I have a Marvel Unlimited subscription, so I've been reading soooooo many comics. I think I'm, like, two comics away from finishing their House of M event from... '06? I dunno. But I've heard House of M was one of Marvel's best events, and for good reason. House of M was fantastic. I love how it flips everything on its head and changes everything and just ugh. Now I'm moving onto Decimation, which is the event immediately following House of M, and I wanna see how House of M affected everything.
The one teensy complaint I have with House of M is I don't know all of the tie-ins. They're all listed on a website I found, but some of the more obscure titles have characters that I just don't know. xD So it makes it a little hard to get invested in those scenes. But if that's all I'm complaining about, I'd say it was a pretty good event!
