most of the engines don't pass my simple test - enter name of movie and i expect to see aggregated basic info and ratings of movie at least from 2-3 websites without opening them

However, the real reason your wish will not be granted is that those 2-3 websites are absoluely opposed to such a scenario, as people will not visit their websites anymore. If I remember it correctly, Google had that feature years ago and was sued by Yelp(?) because they basically stole all their traffic.

unless there will be another engine which will provide me with same information as you can see on right side of screen I am not even bothering to try it, it's such basic feature that I think every engine should provide it
Google has this feature, so I am not sure why they can and others can't.
