I felt Covenant was overall bad..not helping was that the trailers and prologues revealed too much of an already predictable storyline (especially if you've read anything about unused concepts from previous movies). The characters were stupid, like b-horror movie level. Like you wouldn't trust these people to go to the grocery store, let alone in space. I mean, for the crap AvP movies got, most of Covenant is about the same level of b-movie . I heard Scott was aiming for a b-movie feel. But wasn't this franchise once held in some esteem (I guess that was 30 years ago at this point).
Can't even blame Lindelof for this one. Some blame fans for wanting the more traditional alien in movie after Prometheus. My problems with Prometheus had nothing to do with not seeing the traditional creature. Covenant made Prometheus look better because at least it tried to do something...even if I didn't care for what it did.
The effects were good...except maybe one part that reminded me of the SPACEBALLS diner scene...maybe that was intentional. Fassbender's performances were good, though noticeably older looking for an android that doesn't age.
I'm not sure what can be done to make the franchise interesting or engaging again. It's like the Terminator franchise.
