Doesn't "too much CGI" really mean the CGI was wack? I don't remember anybody saying Avatar, for instance, had too much CGI.
Movies like Avatar, the Star Wars series, the Harry Potter series and Lord of the Ring series all use CGI extensively but it's a seamless and creative blend of both acting, editing, and cinematography to help tell the story.
Movies like Battle: LA, 2012 and Transformers also use CGI extensively but its overuse can be obtrusive and sometimes even annoying and can barely tell the story well. Now, this comparison may very well be subjective, however, that's what I experience whenever I'm viewing big budgeted, special-effects ladened movies like those. It's a sensory overload to me.
There is this one shot in this version of The Thing I saw in the trailer where a vehicle (looks like a truck) is falling into a collaspsing, darkened shaft and my immediate reaction is,
"Oh, that's CGI...!"
I can only imagine what the rest of the movie is like.
