My apologies. I didn't mean it as an insult. I shouldn't have used the word "dumb."
A character can be made for kids, but still liked by adults. I watch cartoons regularly, personally. Love Superman the animated series, etc. Semantics I guess, but still. I think Krypto is great in comic panels and in animated shows. I don't like him in cinema, because I think it's more likley that Krypto will make the film feel like a cinematic cartoon, rather than the film making Krypto look like a real world super pet.
Saying that a 'super-pet' concept is cartoonish isn't really a hot take. Nor is it controversial to say that the more cartoonish a story becomes, the harder it is to make the stakes feel real. That's the risk.
The last remaining Krypton surviving and landing here on Earth is far far far more believable than that same lone surviving Krypton somehow finding the last surviving Kryptonian dog. I'm sorry. That's silly. It's like saying, "since we now see a monster destroying the city, let's also put in a clown who pulls out his secret super balloon bazooka that can take it down." The idea that just because we can believe one thing means we can believe anything no matter how ridiculous is just not true. People disconnect when you ask them to suspend disbelief too much.
I mean, I think it's clear that Gunn knows how to hit the character beats in a way that Snyder never did, so I feel confident that Gunn is going to make us connect with Clark emotionally, which is what never happened with Cavill. And after that, everything is pretty much just extra. But Gunn is also interested in making an extended universe, and things like Krypto can slowly erode the appeal, because the stakes become hard to increase. I think the film can survive Krypto, but he's a bad omen of things to come, and ultimately, it'll become a bigger problem.
