I disagree. To be honest, I love the close-up sneak peeks - and it's very much how the Channel 10 era BB used to entice us.
I'm somebody who loves seeing the new house for the very first time during the Launch show. The last two seasons of BB on Channel 9 have revealed full interior photos of the house a week before the show aired, leaving no anticipation for it at the Launch. While I don't doubt they'll do the same again this year once the HM's are in Lockdown, I actually prefer not to see the house beforehand at all.
The close-up shots keep us guessing and add mystery about what could be inside. There'd be no speculation or excitement if we saw everything in advance.
I kinda hope it's the ONLY official sneak peek we get of the house this year.
