Review: Heather Graham couldn't play a convincing lesbian if her life depended on it. Who do the producers of the movie think they are? the ABSOLUTE WORST, most UNREALISTIC movie i've seen in as long as i can remember. This movie is so bad that i felt compelled to sign-up on IMDb and make sure the rating of this "film" drops.omg i'm Heather Graham, i just kissed a drunk chick, so while she's passed out i'm REALLY going to pace around my room for HOURS asking myself frantically "WHAT HAVE I DONE?!".. Jesus heather, get over it and grow up... and i'd like to forward that same sentiment to the idiot producers... and while i'm at it, instead of this movie being all about an pathetic excuse for a coming out story, perhaps it would have been more suitable to focus the plot onto a character who's mentally unstable... like your so-called "lesbian" character... after all, i know the first time i had gay sex, when i left the next morning i jumped to the sky in excitement in the middle of the street... honestly b*tch, get a grip... WHAT A JOKE! and please note there are many many many more flaws and appallingly stupid aspects to this lame flick, but i'm so sick of even thinking about it anymore. bottom line, if you're a smart person you'll hate this movie, and if you're not a smart person, then you'll love it... it's as simple as that. Question: is it a negative review?
yes

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?
yes

Review: If there was a 0 stars rating i would gladly hand it out to this absolutely horrid pile of waste. The fact that the actual summary is perfectly fine and that if it had been made different it could have been brilliant only makes it worse. The basic task of locking up a group of people in an experiment chamber is fine, but WHERES THE EXPERIMENT? All i see is a bunch of unintelligent surfers and blondes chatting about music and culture i don't know or want to know about... The challenges are pathetic and silly. The whole point of reality TV is to show REALITY. If you set a 'challenge' don't make them play with exaggerated props of food and stereotypical cultural elements in 'friday night games'. make them do an actual challenge. And as for 'earning' prize money, thats fine, if they actually earnt it! These people are nuts. If only they would make the show better, the actual idea would be glorious. But that ain't gonna happen! Question: is it a negative review?

yes
