this be the first sci fi series that i have seriously become hook on since star trek and ( and i haven not watched trek in year ) . it take the invasion theme in somewhat different direction and but have do it in a very exciting way . it also borrow from soap opera format and where it continue the arc throughout the entire year run of the series . the cgi definitely doesn not overcome the plot or the character and except for nim and the fledgling creature who be a pet with definite attitude . ( anything that would show what he really think about the neighbor yippy dog be a 1 in my book . ) he be a stroke of genius . i be leave at the end of the finale ask question ( intelligent one and i hope ) and cross my finger and toe that nbc or someone else ( sci fi and maybe ) will continue to run the series and answer those question . a really great and classy show .
