The first episode is currently streaming on Hulu. Hulu doesn't make all episodes available of their series at once. Each episode is available on Wednesdays.
If the rest of the episodes are as good as the first one is, it will be very worth a watch.
Portion of a review in The Atlantic:
The Gripping History of The Looming Tower
The new Hulu series is a suspenseful, star-studded excavation of the failure to prevent 9/11.
SOPHIE GILBERT MAR 1, 2018

Produced for television by Lawrence Wright with the Oscar-winning documentarian Alex Gibney and the veteran showrunner Dan Futterman, The Looming Tower is a taut, tense restaging of the internecine squabbles between the FBI and the CIA in the lead-up to 9/11.
Like Wright’s (Pulitzer Prize-winning) book, it makes the case that the failure of U.S. intelligence agencies to share information thwarted any chance they might have had of stopping the attacks. But where the book focused primarily on the people who conspired to orchestrate the worst terrorist attack on American soil, the series reorients itself around the people who failed to stop them.
On one side is John O’Neill (Jeff Daniels), a larger-than-life FBI counterterrorism chief grappling with the increasing threat of al-Qaeda. On the other is Martin Schmidt (Peter Sarsgaard), O’Neill’s CIA counterpart. O’Neill was a real person; Schmidt is reportedly an amalgam, although there are reasons beyond his initials to deduce whom he’s based on.
From the very first episode, O’Neill and Schmidt are at each other’s throats for reasons that are hard to ascertain. Schmidt guards CIA intelligence with fanaticism, while O’Neill resorts to spewing profanities and epithets when he can’t get what he wants.
