It’s derivative, it’s predictable, and there’s nothing in it that you haven’t really seen before. But “Book Club”, starring screen legends Diane Keaton, Jane Fonda, Candice Bergen and Mary Steenburgen, is an amusing film that doesn’t take itself too seriously. In terms of plot, 4 friends decide to spice-up their sex life after reading “50 Shades of Grey” during their weekly Book Club gathering. Cue the awkward moments and the embarrassing ones too (think the viagra scene in “Little Fockers”). Really, there isn’t much more to the film. It has a (mostly) relaxed feeling, and it populated by good and familiar actors (I especially enjoyed seeing Richard Dreyfus and Andy Garcia here). There are definitely times that its “cuteness” feels forced. But no matter. If you like these actresses, you’ll definitely enjoy seeing them all together in one movie. But ultimately, you’re bound to forget it as soon as the credits start rolling. I know I did.
