They are both not even good movies especially Requiem.
The pitch of Paul Anderson's movie is interesting. Not well made but interesting. The film photography is good and the movie has some cool scenes with very good Fx (Even if ADI's Preds are horrible): The Preds arrival, The battle with the Queen, Overclocking effects... I don't know what you thought about the CG Queen and Aliens but I found that really good.
Of course Requiem is the straight sequel to the first one but: The little town, The hobos, The bully, the sheriff, the veteran, the little girl, the sports shop, the school battle, the Predalien... are too much for me. It's not possible. The shot of Wolf in front of the sports shoes in the shop is one of the most ridiculous thing I saw in a movie.
