I think a lot of what has worked in the show has been helped by Jennie's amazing subtle reactions whilst keeping that rictus grin going (i guess eye-acting is a thing?), and without that it felt a bit off. Missed Ruth as well, it felt there should have been a finale to that. The fashion bit was strong but after that I didn't think it was that strong outside of a couple of one-off lines, although his attempts to stage-manage Simon on live TV were pretty good.
Overall the sereis was a decent attempt to bring Alan into the world of modern TV (looking back, KMKYWAP was so of the TV of its time and this was a nice update to that).
And we'll always have Irish Alan. Ha-ha!
