Review: I believe this is the most powerful film HBO Pictures has made to date. This film should have been released in theaters for the public to view on the big screen. It is available on video so make sure you look for it and check it out. Chris Gerolmo did a great job with the direction and the screenplay. The performances from Stephen Rea, Donald Sutherland and Jeffery DeMunn are flawless. A masterpiece of the genre. Question: is it a negative review?

Ex Output:
no

Review: ...but I regret having seen it. Since the ratings on IMDb are relatively high (and they must also have been relatively high on Netflix), I guess I put it in my queue because it is advertised as a gentle comedy from the UK, a category that has produced many films I liked immensely. "Saving Grace," on the other hand, falls into the category of laugh-less comedies usually populated by Hollywood movies produced and directed by the talentless. Brenda Blethyn is a capable actress, and I have liked her in other movies. The concept -- a gardener growing marijuana to overcome the penury she finds herself confronting after her husband's death -- does not offend me. Notwithstanding the strenuous efforts on the part of the cast to produce humor, the film falls flat on its face (falling flat on its arse might have been funnier) as far as I and my wife were concerned. Be forewarned, oh gentle reader, not all offbeat British comedies succeed. This one is a dud. Question: is it a negative review?

Ex Output:
yes

Review: Is this your typical women in chains navy transport love story? Maybe, hell, you know how the formula works by now, pretty woman is introduced in to a picture, someone has to fall in love with her.I think this film does follow some typical story lines, but that doesn't say anything about the content. There are great scenes with Crispen Glover, Dennis Hopper, and Gary Busey, although short. Some things didn't make sense, such as the need to get in to random fights, but it is entertaining to watch, the fights were actually well done.This is definitely a comedy foremost, but it does have a lot of good feel to it. The humor is well balanced, you won't hurt your stomach on this, but you will keep a smile.There is a little bit of steamy action, so not one for the kids. Question: is it a negative review?

Ex Output:
no
