Speed Racer is done to style of the cartoon and is meant to be that way. Between the story itself, character arcs, and the cinematography, I give it 5 stars. The only bit I have some issue with is a few too many flashbacks at the beginning of the film but I consider it a reasonable evil to get the viewer up to speed on the setting and current story arc.
Lost in Space has all of the original actors in one place or another except the original Dr. Smith. It seems like it was intended to be the movie/pilot that the original show really deserved and I think that they did well enough with it that it really should have had a series with the same cast, picking up where the movie stopped. They even managed to have reasonable character development within the running time - something that few too movies even have the capacity for since they require so much plot or action to deal with plot holes.
Neither one uses the "blockbuster formula" so they didn't do all that well in the box office but with nearly every movie following that formula to the point of it becoming cliche now, I think it's a refreshing reminder of stories for the sake of the story and uses all the elements correctly instead of feeding off our hard-wired evolutionary desire to see action, death, destruction, and mayhem despite both of them having a reasonable share of each.
It's a tie between this one and this one
