Recently, I tried to watch really old, really girly tv shows like Winx Club and W.I.T.C.H that I would have gladly watched as a young brat but nowadays I find dull and a little off-putting (except for W.I.T.C.H's second season, that was okay). I decided to seek out the W.I.T.C.H comic book, though.
I've been watching the Sailor Moon remake, too. That's something I wouldn't pass up, though I find myself missing the old anime, mostly due to the old gags that seem to be missing from the remake. (*collapses* "Do you want me to take you to a hopsital!?" "...I'd rather go to a restaurant...") Luckily, the old anime is getting a re-dub, and since the new anime updates at a super-fast rate of one new episode every two weeks, that is another think I look forward to. Yes, it's also kinda girly but in a more bearable way that newer magical girl shows tend to avoid (Looking at you, newer Pretty Cure seasons).
As for old cartoons and such, like the above 90% of them are either boring or stupid to me nowadays (Dexter's Lab, Fairly Odd Parents, Power Puff Girls) but there are a few I miss a lot and will watch them if they come on TV (Ed, Edd n Eddy, Courage the Cowardly Dog, Oban Star Racers)
But yeah, it really does bring me back. Not too far since I haven't really gotten to the "pay bills and rent" phase of my life yet aside from simple gas and tuition payments. A time where I didn't have to worry about job interviews or cleanliness.
