However, 'Far Away Places' feels like it needs at least two viewings to even get a handle on what was going on as Matt Weiner took us from the swinging '60s to the trippy '60s and our first full-on Mad Men drugs experience.
Don, Peggy, Lane, Joan and Pete have all stolen the limelight in previous weeks, but 'Far Away Places' was very much all about Roger.
Don and Megan's relationship was put under a huge strain - he feels like she's in a master-servant relationship, he wants some love from her and treats her like a '50s housewife rather than a young '60s go-getter. Peggy still can't flog a baked beans advert to Heinz for love nor money and she has a mini Draper-esque breakdown as a result. She rants at the client, resorts to booze, rows at home with her boyfriend and does something unsavoury with a gentleman in the cinema that will put you right off your popcorn.
But as we mentioned, this episode was very much Roger Slattery's time to shine. Don and Megan's creepy cat-and-mouse game and power-playing was intriguing, but after weeks of hearing about Roger's boring homelife it was brilliant to finally witness a glimpse of the Sterling marriage in action. And of course, we got to watch Roger under the influence of LCD.
It was fantastic to see Mad Men taking some risks in its style, shape and tone. Some hardcore fans of the show may not have approved of the deviation from its standard position of naturalism, but the wonky plot timeline and jumpy twitches between scenes worked for me.
Roger thought he was back at the 1919 World Series, he had musical drinks bottles, he was imagining Don in the mirror and he was able to break off his relationship with Jane in a loved-up, blissed-out hippy fashion.
The silver fox of SCDP has spent much of season five out of control and shedding authority and influence by the day, while Pete Campbell clips away at his heels. Sterling and Don have lost control of the office - Don through not caring, Roger through his own ineptitude and laziness - but it would appear that Roger's LCD experiences may have re-ignited Roger's mojo.
Not only is he footloose and fancy-free with the women again (any chance of a happy ending with Joan?), but his "it's going to be a beautiful day" final line appeared to offer a glimmer of optimism for his future at the company. Have his eyes been opened to the possibilities and ideas of the new generation?
One final note: Can we have some more Bert Cooper (Robert Morse), please? Everybody else has had their own special extended moments or storylines this season, but Bert remains at the sidelines. The mystery surrounding Bert and his dry one-liners whenever chaos is happening around him are utterly perfect, but we still have a burning desire to see a bit more about what makes him tick. Who is the real Bert Cooper?
Mad Men continues on Tuesday nights at 9pm on Sky Atlantic. It airs on Sundays in the US on AMC.
