The only way you can hate Mario is that you suck at platformers TBH.
Or maybe you just don't like Mario?
I like some Mario games, and once I finally get my hands on SMW I'm sure I'll love that (as well as SMRPG once I get that). But Mario really isn't even a likable character to me. He's a plumber, who's supposedly Italian but really only insults Italians by saying stereotypically Italian phrases (which offends me, since I'm 50% Italian).
You don't have to be bad at the games to dislike them...
Also, another possible explanation for a natural dislike for him could be that you were started off on gaming with Sonic. (Kidding, that's not really why I dislike him at times. Although it's not impossible.)

Or Peppy will DO A BARREL ROLL and make something wrong with the G-Diffuser!
Second Life. To be honest i'm sure if thats a GAME at all.
I don't think it is. In fact, I know it's not.
Super Metroid (really, couldn't get into it at all)
There are a lot of hard-to-get-into games. Once you get into it, though, it's awesome.
You should give it another shot.
Super Metroid was the best Metroid. It started the super special attacks before prime did. & invented Hyper mode.
Exactly, Super Metroid > All.
How did it invent Hyper Mode, though?
No offense, but that's a truly awful reason to dislike a game. If you enjoy playing a game, then enjoy playing it!
You'd be surprised how much annoying fanboys can make you dislike a game.
-Metroid on the NES is still the ONLY good Metroid game.
Um...what?
Metroid is one of the few series's where the first game is actually widely agreed to be not as good as some others. Or at least, I thought it was widely agreed as that.
While Metroid is a good game, it's severely hindered by a lack of features that would've been very convenient. Crouching is probably the most notable one. Also, it's rather short and just has Ridley, Kraid, and Mother Brain for bosses. Which brings me to my next point; at least on the original NES, during the Mother Brain fight there are so many items on screen that it lags like crazy and makes the fight even more difficult. More difficulty would generally be better, but lag causing that increased difficulty...is not good.
I'd be willing to understand if you thought that it's the best Metroid game...but how can you possibly say the only good one? Super Metroid at least is beyond awesome, if you wouldn't accept any other of the games as good. Fusion is also awesome, but it's a different type of Metroid and it's sort of an acquired taste, I suppose, so I wouldn't hold it against you for disliking it (despite the fact that it's probably my second favorite Metroid).
Looking at the rest of your post...you seem extraordinarily nostalgic. I mean, retro gaming for the win, but jeez, you even said that Sonic 3 and Sonic & Knuckles were bad.
Games that I dislike that are popular?
-SUPER MARIO GALAXY. It's in caps for a reason, I hate it that much. It was a mediocre game, at best, and it gets the treatment of a god. Not the best Mario game by far, even though I hear that a lot. And the fact that even one person has claimed it to be the best game ever makes me lose all hope for humanity.
-Halo. Not that bad, and I do intend to buy it for my 360 at some point, the fanboys just annoy me. Also, I do find it to be overrated.
-Guitar Hero. I find the whole concept to be pointless. Also, there's a good number of idiots who think that Guitar Hero makes you good at guitar, and this annoys me to no end.
There's a reason a lot of real guitar players aren't good at Guitar Hero. They are entirely dissimilar.
-Sonic and the Secret Rings. This one is actually divided, there are a number who hate it and a number who don't. I don't understand the people that like it, and I hate them because it's getting the godforsaken game not even just a sequel, but an entire spin-off series.
-Brawl. Obvious.
-Final Fantasy games. I don't find them to be that fun at all, and the hype they get only annoys me more. Not to mention there are so many Final Fantasy games it's not even funny.
-MARIO PARTY. It's been milked to death. JUST LET IT DIE, NINTENDO!
-Mario Spin-offs aside from RPG's. What's Mario going to do next, play Lacrosse on a chessboard whilst simultaneously dancing? Seriously...
I'm sure there are more, but I can't think of any more at the moment.
