Or just being themselves ?

If they're just being themselves there's something refreshing, admirable and likeable about it.

Or is their gameplay so brilliant I just can't see it ?

If they don't manipulate or handle situations to their advantage they aren't gonna score "gameplaying" points.

Would have given them 10 for gameplaying (i.e. don't need one) but made a cockup on the cash twist where they didn't take the biggest amount possible.

Similarly Dex would have been higher for gameplaying except for 99Kgate and how he sometimes is too silent and coy.
How he handles the next few days could be crucial.

Here's how I rank the housemates right now...

.................................Dexter.......Gina ......Jack.and.Joe....Charlie......Sam
Intrigue/Interest..........10.............8...........7.... ...............9............6
Entertainment/Comedy...9............. 8..........9....................6............5
Playing.a.GOOD.game....6..............9..........7 *.................10...........8
TOTAL........................25...........25...... ..23..................25..........19

* Not playing - just being themselves ?

Deciding factors (just for me...)

- How Dexter handles Charlie's onslaught/manipulation
- Whether Gina can keep her cool, handle Charlie and warm more to the public
- Whether Charlie can be more fun loving.
- Sam - whether he can push that moral highground to the max(hey it's a game !) or be called out by Dex.
- Jack and Joe - not sure but how they react to people (like Charlie and Gina) vying for their support could be interesting.
