I liked this 21 Jump Street spin off. It wasn't quite as good as 21 Jump Street but it was still entertaining. Richard Greico has done a few things since then but I haven't seen him in many movies.
Actually, Booker was no better nor no worse than 21 Jump Street. Maybe Johnny Depp was a more talented actor who has gone on to a better career, but he didn't get a spin off (or possibly didn't take on a spin off) the way Richard Grieco did. If I recall correctly, the Nielsen Ratings boxes not being used correctly at the time is what led to Booker getting cancelled before it should have.
