I thought it was a good, entertaining game. Munster really showed up in front of a big crowd at Thomond Park. I'm always surprised at some of the crowds the Irish are able to muster for these kinds of exhibition games. Their U20s also regularly play for crowds of 7000+ people.
On Plummer, I think he really benefits from a secondary playmaker in the backline, like Perofeta or Sullivan at the Blues, especially in the face of an agressive defensive line like Munster's. With Stevenson at fullback and Tupaea at second five, there wasn't a whole lot of secondary playmaking going on. Stevenson can act as a playmaker but he didn't get much involved in this game. The Georgia game might see Love or even Jacomb get a start at fullback (if Love isn't available).
And finally, the refereeing was pretty shocking at times. Not quite as bad as Craig Evans in the Scotland Fiji game, but some of the decision-making (like the Farrell-try or the Kirifi-non try) was genuinely ridiculous. Without some of these decisions, you'd think the gap would've been substantially bigger between these two sides.
