Haven't seen those sequels before. Overall I enjoyed it very much. A very decent franchise that could offered lot more & still can.
One of the most impressive things about the last & 4th part:
Oblivion is the way they were able to incorporate so much unused footage from the original (19 years earlier!) into the film. Despite the time difference, the new film and the old footage work together perfectly, and that is a really cool thing to behold as well as might be quite emotional for some of the cast & the crew members, specially Michale Baldwin who played Mike.
