[EX Q]: Review: The first 45 minutes of Dragon Fighter are entirely acceptable and surprisingly watchable. The characters are believable and interesting. The cloning lab looks really high-tech. After that, it all collapses. The characters start behaving idiotically, and a new subplot is introduced from nowhere about a fusion reactor (and this is supposedly "present day") going critical, the only plot justification of which is that it is required to kill the dragon - only it doesn't. The finish is incredibly weak. One wonders what made a movie that started out so well turn so wrong.All the characters except Dean Cain are played by Russians. This results in some weird situations and details, like the character being played by Vessela Dimitrova being called "Bailey Kent" despite her heavy accent (and despite her, on one occasion, inexplicably switching to *Spanish*!).Because of the decent start, I considered rating this movie a 5, but it really was more disappointing than that, so I only give it 4. Question: is it a positive review?

[EX Q]: Review: We all have seen some unending epics in our times, but this one really tops them all! The movie is so long and so slow, that, just to put things in perspective, i felt a lot older when i left movie hall, than I entered it. At almost 4 hours length, it could have rather been made into a tele-serial.What starts as a promising comedy slowly loses its pace. Nikhil advani has woven the plot around 6 love stories and he cant make justice to any one of them... There is no interconnection between them to start with, and links shown in last 20 minutes just seem to be forced to connect the story.Situation is made worse by Silly dialogues (most of them repeated in Hindi cinema over years)and stupid cinematography.Priyanka doesn't realise that she actually needs to play her role rather than just looking glam on screen... An utter waste of beauty without acting skills.And then there is loud-is-humorous Govinda & my-face-twists-better-than-jim-carrey Akshay Khanna who keep belching at the top of their lungs to irritate already tired viewers.Only good part in movie is John & Vidya's love story & nice acting/comedy by sohail & Isha. But they are so good at their roles that just these two couples could have justified the movie without jumbling it with other bunch of characters. Their brilliance gets lost in the midst of other substandard plot lines.My guess - Director was making two separate movies(may be more!) and some beginner assistant mixed up all the records, beyond a point of sorting them out, so director was left with no choice to show it all as a single movie...Watch it only if you want to test your patience!!!

[EX Q]: Review: Jennifer Jason Leigh and Mare Winningham are a good match portraying vastly different siblings, but only Winningham is able to bring something convincing or substantial to her role. Leigh, playing bar-band singer and alcoholic Sadie Flood, constantly leans on older sis Georgia, an acclaimed folk singer in the Joni Mitchell mold. Perhaps due to her double duties as co-producer on the film, Leigh seems to have boxed herself into a corner: she isn't credible as a singer and, even if this is intentional, gives herself far too much screen-time at the microphone. Probably hoping for a tour-de-force, Leigh is wire-drawn and nervous and jagged; however, we simply do not see any talent within this character (Leigh is obviously a solid actress, but she makes decisions here that wall us off from her). If Sadie had even the slightest bit of charisma or appeal, we might be able to buy into the concept that she gets the (small) breaks that she does. As it is, the likelihood of her ever getting up on stage is slim. Director Ulu Grosbard crafts a few intense dramatic sequences, and the editing at the finale juxtaposes Sadie's bar performance with Georgia's sold-out arena show--both singing the same song--and it's a sadly nuanced moment...but really, what's the point? *1/2 from **** Question: is it a positive review?
