Well, the thing is, it's fairly obvious. Whereas games can skip the plot and rely on gameplay, movies cannot simply rely on visuals. It's impossible.
In Death Race 2000, in addition to the main plot, you have sub plots about revolution, personal involvement in the race, and betrayal. There is plot in that movie. And when you can get big name actors, you have a budget to make more frequent action scenes.
It seems to me that you cannot understand the basic difference between a game and a movie. In the game, you can blow up a guy and have him show up at the next race and not question it. In a movie, unless you throw in some pseudo-science about how they survive the explosions, it does not work. So after one race, most of the antagonists would be dead. In a game, you have an instruction manual where you can write the backstory for all characters. In a movie, you can't do that.
Videogames are an active experience, you take part in the action, so you can't sit around and wait for the action to happen. Movies are passive. And for everything to work together, you need a plot. You can, just have 5 races, with lots of explosions,and call it a movie. It does not work like that.
Also, it's an independent project. You can't compare one of these to a hollywood production, they are not on the same level. Do you compare flash games to multi-milion productions? Would you review a 4th grade play like you would review something from a big budget company?
Also, I'll stop being condescending when you stop exhibiting so much contempt for a fairly cool project to do. Just like people here don't piss all over some new remixer's WIPs, you should not piss all over his project.
