N52 was happening right at the time I was getting back into comics and the first couple o comics I bought were Green Lantern, Flash and Red Lanterns. I'm still reading @12 and really enjoy them. I hadn't read comics for 20 years so I dont have that connection with past continuity but can understand people not digging it.
If you don't like it anymore then you should definitely check out some other companies. I love Image and I'm constantly adding their books to my pull list. And if you want superheros you should check out Valiant. I don't read too much Marvel but Elektra and Punisher are solid titles.
