This has me in a weird position. On one hand, I do think that another director, down the line, would do a great job with this. I mean, the proof is in the pudding-these characters, these stories, they didn't survive for 40+ years just because all the other kids were doing it. And as such, providing there are no incredibly drastic changes to the formula [and a sufficient budget and time frame], you've automatically got a good film. It reminds me of an old saying my grandfather used to tell me: "Even if you crap gold, it's still gold."
However, considering it's just two movies into the franchise, it's a bit early to be jumping ships. Sure, there are a few GLARING problems with what we have now, but it could be worse. We could have nipples, people.
