Lisa got off far too lightly last night... on both shows.
As for Davina on BBBM (and side-kick Brian): don't think she does a good job at all.
My heart sinks every time I see John M too. He starts with the hard line, but by the end of the show, he and evictee are always best buddies.
Some guest hosts last year were truely awful, but some were excellent: it's where I "discovered" Michael McIntyre, for which I am always greatful
