This is a perfectly good movie. The comparisons to The Covenant, Guy Ritchie's movie with Jake Gyllenhaal are understandable, and while there are some similarities, it is not a like for like by any means. There are in fact many differences. I won't spell them out for fear of giving spoilers, but if you watch both movies you will get my point. Gerard Butler does seem to be the go to guy for an awful lot of action movies over the last five plus years, but there is a good reason for that. He meets the requirements of a Hollywood hero very well; handsome, likeable, tough and and pretty decent actor for the most part. I enjoyed the movie and would recommend to anyone who likes action/military type movies.
