Translate the following question to SQL: Find the titles of items whose rating is higher than the average review rating of all items.

Schema: CREATE TABLE item (
    i_id INTEGER NOT NULL  PRIMARY KEY,
    title varchar(20)  DEFAULT NULL
);

CREATE TABLE review (
    a_id INTEGER NOT NULL  PRIMARY KEY,
    u_id INTEGER NOT NULL,
    i_id INTEGER NOT NULL,
    rating INTEGER  DEFAULT NULL,
    rank INTEGER  DEFAULT NULL,
    FOREIGN KEY (i_id) REFERENCES item(i_id),
    FOREIGN KEY (u_id) REFERENCES useracct(u_id)
);

CREATE TABLE useracct (
    u_id INTEGER NOT NULL  PRIMARY KEY,
    name varchar(128)  DEFAULT NULL
);

CREATE TABLE trust (
    source_u_id INTEGER NOT NULL,
    target_u_id INTEGER NOT NULL,
    trust INTEGER NOT NULL,
    FOREIGN KEY (target_u_id) REFERENCES useracct(u_id),
    FOREIGN KEY (source_u_id) REFERENCES useracct(u_id)
);

SELECT T1.title FROM item AS T1 JOIN review AS T2 ON T1.i_id  =  T2.i_id WHERE T2.rating  >  (SELECT avg(rating) FROM review)
