should I just save my money?

It now seems the verdict is in and that RS has failed to deliver the movie he's promised. There are quite a few reviews floating about and from my observation the bad reviews outweigh the good. I still plan on watching the movie just so I can judge it for myself but the common thread among all the complaints seem to be 1) that it was a wasted opportunity and that Lindelof's script sucked 2) the acting was horrible, aside from Michael Fassbender 3) the score sucked and 4) the movie left more questions than answers. Someone had made a comparison to The Thing prequel, which made me nervous, because I too thought it was horrible. I will not judge this movie until i've seen it first but I can't help but feel nervous about it. Does anyone else feel the same?
