This is slowly getting interesting
I never knew The Green Lantern knew Chinese (he said Hanzi). Also, considering the symbols used, I'm surprised he deduced it to be of Chinese origin. Of course, I guess you can still say Hanzi, considering they were only one symbol. I feel bad for Batman. He just drives forward, seeing the fire-breathing T-Rex, only to get stomped on. I'd like to also know what those darts were that went inside The Human Torch.
The animation has gotten noticeably better compared to the first SHS. As you've stated, there's sound synching problems. That's not -that- bad of a problem for me. As others have stated, Captain Marvel went down. And he was in a team. This shows that the enemy is strong, sure, but it kind of makes those who can believe this to feel that the enemy is too powerful. As for the skeptic side of this, it makes it seem as if this was some unintentional mistake, or some poor planning.
I like the voice acting. It really fits, in my opinion. I don't really like The Human Torch's eyes though. Both of them didn't seem to fit. Also, The Hulk lost the first time against the fire-breathing dinosaur, and he's supposed to be the strongest in the Marvel universe . . . well, I mean, he's even able to fight Thor on par. The Hulk Vs. movies show that, anyway. The strength seems to be inconsistent here, but it also shows that the enemy can summon creatures at that caliber.
All in all, I can't wait for the next part, and I'm enjoying the series so far. Keep up the great work! ^.^
