One of the best tv series in drama category. No better tv series was made in drama category ever... and now Hawaii Five-O - Season 2 is accessible to watch online for free. That's really great if a tv series can keep me focused for the whole duration, that's what Hawaii Five-O - Season 2 is doing. The tv series is great, it does not get boring, Hawaii Five-O - Season 2 does not get long and although it is not an original production, good acting and skilfully written script make it worth watching. A very positive for me was the role of the main character. this director's tv series play on emotions and are able to move a more sensitive watcher. You don't need to be a drama fan, but it's just worth watching online. Download or watch in HD quality here.
