Really good watch, could watch again, and can recommend.
Heather Graham, Angela Kinsey, and Stephanie Beatriz play off each so well in this. It honestly reminds me of "Bad Moms" without kids and less ridiculous.
This is a "chick flick" in its truest form. It's not good (or bad) because of that, but it's just a focus of the movie, feeling lost and empowered as a woman character. They make an excellent choice in using Chris D'Elia to portray the chauvinist industry of movies (if to a bit of an extreme).
This is also the second time I've seen Johnny Knoxville play a priest, unsettling both times.
While the concept of candle based witchcraft is somewhat intriguing, it's just a mechanic (same as the workshop) to interweave the multiple story threads. It would be a little more satisfying if they had a more legitimate bond than "we met this one time" established at the beginning of the story. On the other hand it makes the formula flexible enough that it could be that they joined through AA or a convention, so I can see the use of doing something like this.
The movie is charming, and it's good (refreshing in the very least) to see feminine perspective of a romantic / sex based humor of this quality.
While I think this is better than average, it's not quite "Bad Moms" level of humor.
