No, watch the movie also.
It's not a page by page adaptation of V for Vendetta but there are a few sequences lifted directly out. A few changes in character backstory but the theme and tone of the movie contain the spirit of comic itself.
The film was overly bashed upon release. For some reason it had to be a literal translation for some and their minority voices were just loud at the time of it's release. The appreciation for it you're now seeing is proof of that to an extent.
I do blame the marketing team for billing it as an action film when really it's more of a drama with some action pieces. That may have also contributed to the non-fandom disappointment with it at the time.
