You're absolutely right. But, I guess I am expecting less attention to the traditional elements of costume and set if this is going to be a huge diversion. A good chunk of the cast looks like they walked right out of the original series (with certain updates). If this is a parody, I get it. If the attention is to mock those looks, it's one thing. But I don't think any of us were thinking that was the case after seeing the cast photo. If Burton is going for his own radical spin (that's not parody), I'd think that would extend to set design and costume. I can't see him staying so true to those elements and then turning the movie into a comedy.
They actually went to Seaview to photograph and survey for goodness sake. I can't imagine Tim Burton's crew going to all that trouble just so he could have a script that diverts from the original tone. But who knows? Maybe the beauty of the original series is only skin deep for Burton and Co... Time will tell.
