@Kingston is right that we should refrain from passing judgement before we see what they have come up with. Watching some of the hints they've dropped do
scream ITV in many respects, but we'll have to wait and see how they've implemented it before an opinion can be formed.
My issue with ITV is the lack of real design change and shift to what can be considered a pretty luxurious house coupled with an
extreme use of colour. I always liked how AU (up until 7 mostly) had a different design and theme each season, as I'm sure most others would agree. But perhaps those are a thing of the past at this point. I will say, IF they've borrowed elements from the UK (borrowing/stealing ideas from across the franchise isn't new) I would've thought/expected some originality in their core design ideas. You can build and design a house a million and one ways, especially one that's built as a TV show set. I think it's safe to assume we won't be seeing the high ceilings as seen in the UK since the exhibition centre isn't tall enough to allow it. We'll have to wait and see.
Even if it's like looking at the UK house in a mirror, the saving grace will be how the show is produced and what format changes, if any, have been made. I'll overlook a similar house if they haven't borrowed the format changes adopted by ITV.
