Having seen the film, I think audiences will love it and don't think we should care as much about these reviews anyway. But since they are dominating this board, here is a great article covering the range of reviews:
http://www.newsarama.com/18065-early-man-of-steel-reviews-mostly-posit ive.html
As the article points out, all of the reviews are positive or mixed. Rotten Tomatoes has no outright BAD reviews. No one thinks this film is a failure. Most of the "rotten scores" are 2.5/4 or 3/5. This doesn't end up reflecting well on a site like RT that gives films a black and white, up/down score. If 2/3 of the reviews are positive and 1/3 mixed, that sounds like a decent critical reception to me. And this take on the character was always slightly controversial, so I feel like the number of mixed reviews shouldn't be too surprising. As I already mentioned, I've seen the film and think it's excellent and will really resonate with viewers this weekend.
It's telling that most of the reviews that are mixed come from the position that Superman just can't be taken seriously (and yet, something as fantastic like Lord of the Rings can? This says more more about the reviewer than the film. They just aren't willing to accept Superman as a serious scifi epic based on what they have seen before)
Most of the "mixed" reviews seem to take the film to task for not feeling like the Donnerverse films in terms of tone. I'm A.OKAY with that! Even the apparently 'rotten' views praise the visuals, the acting, and the first half of the film. Cavill is also getting great praise (deservedly so. He rocks in the movie!) Hardly sounds like a critical drubbing
