Bad CGI has ruined so many movies for me. The worst offender I can think of is the most recent film version of The Great Gatsby. It was otherwise not a bad adaptation but the over dependence on CGI just left a bad taste in my mouth. It was just awful!
This was a valaient try at Christie but a bit too revisionist for my taste. The CGI effects are simply no replacent for the real Egyptian locations seen in the earlier adaptation with Bette Davis. Besides, that was a real all star cast, unlike this.
