Enjoyed it a fair bit. Comparing it to Ico I think it has some areas where it does better and some where it fairs worse. Better in that I think it does do a better job selling the bond between the boy and Trico with him being integral to traversal and most puzzles, but it comes with the downside of you feeling like you have to wait on Trico to do something a lot of the time.

Whereas in Ico if you needed Yorda somewhere you could just quickly lead her there. also found the constant control pop ups annoying since it kind of defeats the purpose of the lack of UI, as far as I could tell there was no way to shut them off and I still kept seeing them right up til the end of the game.
