Also, Syrio is the only good character out of them. I mean, Blackfish is cool enough in the books, but very underwhelming on the show. Dunno why people are like, "WHY DIDN'T THEY SHOW SUCH A HUGE CHARACTER'S DEATHA?Q?WE?QWEQ@@!!!!!"

Because he's not a huge character in the show. We've seen him in like, 4 episodes. He's barely been on screen or done anything important. He doesn't matter.
