Ah, I liked this episode! It was nice to have a more light-hearted one for a change - S7s been a little dark for me lately, (Im watching it for the first time) and I'm getting a bit tired of it. So this was a nice relief!
The only thing I didnt like was that it went a little OTT, and a bit cheesy in places. It was great to see Sam having a fun ep, but stuff like "Whats a girl to do?" just seemed a bit false and trying too hard.. But maybe thats just me. Despite this though, the effects were stunning, and I did really like it!
