Finished Episode 4 and damn there's so much to talk about!
For one Shiryu VS Seiya. It goes onto Episode 5 which I will watch shortly after posting this but I would say it is without doubt the BEST and MOST BRUTAL fight of the Galaxian Wars. Everything in this fight is so intense and well choregraphied;I would dare say it beats many of the filler fights later in the series. There's far more exaggerated amounts of blood shed in this fight alone than all of the Galaxian War. This fight alone is a foreshadowing of the infamous "get beaten bad but I keep getting up to keep fighting until I overwhelm them with sheer willpower and repeated failed attacks" that Seiya is so infamous and hated for.
However I got to give it to

in this fight;it is one of the few where he actually
FUCKING uses his head! The way he caused Shiryu's dragon fist and shield to get shattered was an ingenious example of take some to dish out more. He charges at Shiryu, making him think he's repeating his failed strategy of Pegasus Ryu Sui Ken spamming, but instead Seiya bumps his head into Shiryu's shield. In the moment of the fight out of mistake, Shiryu does a right hook to hit Seiya but Seiya is already falling from the impact of banging his head on the Dragon Shield, and Shiryu instead hits his shield. The end result is the Dragon Fist and Dragon Shield gets shattered into pieces. Ingenious move

!
Episode 4 ends with both combatants taking of their cloths so they can fight fairly and continues in Episode 5. I can't help but think Kuru is intentionally creating fanservice when they did this in the fight.

Also I liked the way they started the Episode with those naughty little kids arguing as they go into the Coliseum as well as Saori's explanation of the Cloths and how they represent the Constellations (her speech foreshadows the Gold Cloths that represent the 12 Zodiac Signs).
I can't help but notice somethings I never thought of in my first watching of the series as well as the Rewatch last December.
Did Saint Seiya influence on Street Fighter?
For one, among Ryu's special move was "Shiryuken!!!". Shiryu=Shiryuken? I mean Shiryu's signature attack
Rozan Shou Ryuu Ha is an powerful uppercut that causes opponents to fly feet away in Bronzie level. Shiryuken to is an uppercut that knocks enemies in the air away in considerable distance.
So I think Saint Seiya may have influenced Street Fighter.
Another thing is the training scene at the waterfall.
FREAKING BADASS and a Prime Example of Shonen Spirit.
I understood why Shiryu was like

when Dohko told him to force the waterfall's current to reverse. Against the laws of nature Shiryu responds.Not wishing to disappoint his master, Shiryu goes one for hours and hours repeatedly attempting to do this insane, throwing punches after punches and kicks after kicks nonstop. Finally one powerful kick and Shiryu finally does it-the entire waterfall suddenly stops in its flow literally. Then it starts reversing upward, resulting in a large water dragon flying out of the water.
BADASS TRAINING REGIMENT 
And the way the fight ended was a foreshadowing of just how brilliant the TV series is at picking the right spot and time to conclude an Episode despite the fight still going on. Even
wikipedia praises the Classic TV Series for ending a multiple-episode fight at the right moment that makes you want to watch more and more until the fight finally concludes several episodes later. The way Shiryu VS Seiya ended in this episode was at the perfect timing (just right after they threw their cloths off) and ended with a badass scene (Seiya and Shiryu in fighting stance with the animals representing their own constellations moving as though they were preparing to strike their prey). Seriously the Saint Seiya TV Series is a textbook example of how to conclude an episode despite being in the middle of a fight that continues on in the next few episodes!
Just another thought of mine-the waterfall scene in Ep. 4 makes me call Omega's "Elements" BullShit! I mean Shiryu didn't even have his cloth at the time and he can already manipulate elements!Not even a Bronzie yet! Do they really have to add this "Elements"?I'm calling BullShit here

Off to Episode 5 to conclude what is easily the MOST EPIC and Bloodiest fight in the Galaxian War and which is easily among the best battles in the entire Saint Seiya anime/manga!
