Beware of spoilers too. It's one of those film reviewers who think they have to retell the whole movie to get their points across.
https://www.thefilmagazine.com/creation ... eview-gff/However, overall, Creation Stories misses the mark by a long shot. It’s a messy, mildly offensive exercise in arrogance that isn’t brave enough to make one honest statement.
Well the review mentions Jason a couple of times, and has nothing bad to say about him. But spelled his name wrong:British actors and comedians such as Ed Byrne, Paul Kaye, Perry Benson, Jason Isaacs, Steven Berkoff and Rufus Jones filter in and out of the proceedings in an attempt to add some much-needed spice, but the payoff of their presence isn’t enough to carry the movie.
That's what Jason does in the movie, it looks like.An obscure night out in Los Angeles with Jason Issacs serves as McGee’s rock bottom
I found another one, and it's much better. It's behind a pay wall, though (but for some reason I was subscribed to them... )

Quote about Jason:
Finally, a Rule of Cinema is now etched in stone: there’s no one we’d rather have rock up for five minutes, do a horribly persuasive sketch, and skip off than Isaacs, whose hilariously camp (but also terrifying) performance as Ralph revives a Withnail spirit of clammy aristocratic debauch. There are a million Ralphs in LA, Alan explains. The film plucks this one at random, and you wouldn’t want it any other way.
