I think it was a bad series. Not as bad as BB11 and BB12, but BB4 is far superior to BB15, in my opinion.
I found the last few weeks of BB15 to be dull, BB4 may have been dull, but at least it didn't have twists and manipulations every other day.

I knew BB15 would be bad after hearing all the speculations for it, such as housemates being on the cusp of fame and social media access, but I thought I would wait till it at least started, so I could judge.
The first few weeks it was great. It died after Weeks 3-5.
I also think the theme had something to do with it, in my opinion. On paper Power Trip sounded great, but the producers wanted the theme to involve nastiness and ruthless game players, which set the atmosphere in the house. Not to mention the fact that theme was carried throughout the whole series, unlike Secrets and Lies which was only the first week.
If you compare the nominations tables for BB14 and BB15 you can see how messy BB15 is from all the twists.

The tasks were dire this year too.

The housemates were a pretty bad bunch. Not because they were nasty but because they all had agents and what not.
The only civilians in the series were: Tamara, Pav, Jale, Marlon, and Matthew.

Even though my three favourites were in the final three, it was still a **** series.
It's a shame because it killed the success that C5 had with the show earlier in January and BB14.

If it is back next year, I hope they do things right.
Oh and live feed please!
1 hour live feed throughout a ten week series. The mention makes my blood boil.
