Ebert's movie review was considered "rotten" on Rotten Tomatoes, but he mostly didn't like it for what it didn't do. As far as what he wished to see goes, he ends the review with,
Perhaps the next one will engage these characters in a more challenging and devious story, one more about testing their personalities than re-establishing them. In the meantime, you want space opera, you got it.
He said the movie dealt with "narrative housekeeping." There were good character moments, but all the action was mostly just confronting a larger and better armed Romulan ship.
If you think STID tested personalities and involved deviousness, then you may want to guess the late Mr. Ebert would've liked STID more than ST. Who knows?
