 The film 's effects were conflictingly appraised . Schickel wrote that the effects were " technically adroit " and occasionally " witty " , and Ebert singled out the Bird of Prey as a " great @-@ looking " ship . Sterritt felt that the settings always felt like they were on soundstages rather than out in space , and Denby wrote that more could have been done with Genesis , and that while it was an interesting concept its special effects execution lacked . Kempley appreciated the sets ' low values , writing that " the fakier the sets " , the closer the film felt to its television origins .
