I love Squidward because, well, I could go through the whole list naming off all his typical traits, but that's not very insightful. But it may be what I'm going to do... lesse here...
I like him because, well, he does share my artistic interest, and seems to be quite a thoughtful person - er, I mean, complex. He's the one who'll see through most ploys - whether or not he cares to mention it, is another thing, and I like that about him too. I also like how, that for younger audiences, he comes off as the jerk who's just ruining the fun; then for adults, he makes a lot of sense: SpongeBob and Patrick are annoying. I also like how, despite him being constantly annoyed and loathing everything, he'll turn around and show that he DOES have a heart, and does, somehow, at least watch out for the others. Like he did for SpongeBob in the Pizza episode at the end; or Christmas Who; or even in the movie, when he did realise something was going on and confronted Plankton with it.
Also, he has this tendency to look so gosh-darned adorable when he's shocked - like sudden hugs, or whatever. I like how, when it behooves him to do so, he does come up with a witty comback... For example, during the episode with the Kelp Juice or whatever it was, when Krabs told all the customers that they were no longer allowed to bring drinks from outside in, everyone left and Squid said "That's telling them" after they left. Or how he just remains calm when something insane happens - like in the Viking episode, where they crashed into the KK and Squid's all like, without looking up "May I help you?" or whatever he said.
Also, in Squidville, where he eventually decided that his 'ideal' life was actually pretty darn boring - who wants a world full of just yourself? - And that SB and Patrick's childishness was actually kinda refreshing.
Or in "Love that Squid", where he was so smitten with Squilvia, that he couldn't even speak to her, and had to have SB do it (not really cause he asked, but cause SB insisted, if I remember rightly - I've only seen that episode once) - that was adorable.
Squidward is a complex character. He's inteligent, yet doesn't seem to be able to really make it. Oftentimes, it seems like though he yearns for a 'better life' or more success or whatever, seems like whenever he DOES get the chance, he holds himself back. Seems like he wants to make it in Bikini Bottom, instead of actually moving on. Er, just my own observations... or opinions.
It all just makes him a fascinating character.
While SpongeBob speaks to everyone who has a child at heart - and he's totally fun and, I think, equally complex, he's a... the inner child.
Patrick is hilarious - and something I'm still trying to untangle. He can be mean, he can then be a great friend, he can be dumb, he can be smart... He can do really great deadpans.
Only mentioning them, because I'm trying to make this a thought out reply, instead of just saying "Because I love Squid, and he's best-pony", or whatever! J/K
First, I'm not a kid, in fact I'm in my 30's. I was around when SpongeBob first aired on Nick - and I even gave it a chance... well, watched two episodes - not in order, and don't ask me which, because I don't remember - and I wrote it off and wanted nothing more to do with it. Fast forward to last year, and I started watching it here while babysitting - 'cause that's the show the kids wanted to watch - and after a couple episodes... or more than a couple, I finally gave in. All 'cause of Squidward. I didn't remember seeing him in the episodes I'd watched years ago, but, when he came on and dropped his deadpan, I laughed. And after watching more episodes, I had to give in that the show wasn't that bad, if only for Squidward. Then I really got into it, started watching it as regularly as I could, and started to like all the nuances of all the characters, and finding the plots actually quite fun.
Now, I'll admit, when I watch an episode here, it's dubbed - which means the episode titles are changed (no, not translated, but changed), so I have no clue which episodes are pre or post movie - unless I happen to recognise it from the English episodes, and I do get them random here. (Not sure which season they're playing right now - the last ones I caught over the last two weeks were one about SB wanting a trading card of Mermaid Man and Pat having all five; then the episode where Krabs scares the crap out of Plankton by dressing up as Pearl; and the very last one I caught was when Plankton and Sandy combined their inventions, turning SB the guinea pig, into a puff of smoke and scaring the daylights out of Squidward.)
Uh, yeah, I think I've said enough on the topic. PS I love Squidward :-D
And let this be the last time I have to answer this one, hehe.
