Well, I do like me a good hard, driving rhythm. All the new visuals are also fun for us fanfolk, and the voices are closer to their respective characters. Plus, nothing is actually missing from the theme, so I automatically like it. However...
The synth horns in the beginning completely cover the "ah-ah-ah-ah" we've all grown so fond of. It can still be heard on headphones, and since I'll watch the eps most of the time on YouTube that works, but it's still a sticking point I won't find myself overlooking too easily.
Otherwise, though, I'm all for this. It still retains the charm of the original theme, and the more modern sounding touches don't diminish the end result.
