The 3rd one had a lot more than one timed sequence, but it had one really bad timed sequence where you had to listen to two minutes of unskippable dialogue every time you failed. I don't think they ever fixed that.
The 4th one was sort of clumsy to move around -- neither the keyboard nor the mouse movement was ideal. I think there was one timed sequence, but nowhere near as bad as all those sequences in the 3rd one. MaG's walkthrough tells you where to save.
The 5th one was probably the best since the first one.
