definitely a financial success, but not a successful TOS movie
You know how it gets to be a "financial success?" Because so many millions of people liked it, including about nine out of ten long-time Trek fans.
There's no such thing as a "TOS" movie. TOS stands for "The Original Series."
There are TOS-derived movies, and I far prefer Abrams's resurrection of the franchise to most of the TOS-derived films featuring the original actors because it returns to and revitalizes the milieu of the original series. I loved TOS, not necessarily the ever-more-mannered actors walking through one increasingly-creaky movie outing after another. By the time of The Undiscovered Country the original incarnations of the characters had overstayed their welcome, owing more to haphazardly-conceived stories than to any strengths or failings of the actors.
Abrams's Star Trek is a wholly successful film based on the original TV series - almost purely so, with only the slightest of nods to the convoluted later history and continuity of the Franchise.
