A decent enough cast but with an aborted ending...does that mean an unnecessary sequel?

Rating: 6/10 (10 March 2018)

Mrs. Shullivan and I were looking forward to seeing this move what with all the hype after receiving six (6) nominations and actually winning two (2) Academy Awards on March 05th, 2018. The cinematography and dramatic performances were both very good. We were however categorically disappointed in the outcome.
Yes, Frances McDormand who plays a divorced mother named Mildred who loses her daughter prematurely as a result of a rape and brutal murder is distraught and frustrated with the local Ebbing Missouri police department who are making zero progress on finding out who was responsible for her daughters rape and murder, and what parent wouldn't be frustrated? However Mildred is not such a quiet introverted nor a passive mother. She is divorced from an abusive husband and willing to go to great lengths to literally push the Ebbings police department and especially the town's Sheriff Willoughby (Woody Harrelson) to put a heck of a lot more effort into investigating her daughters murder and to keep her informed into the police department's progress, or lack there of.
I really thought the film had a strong cast including the likes of John Hawkes, Lucas Hedges, Zeljko Ivanek, Amanda Warren, Abbie Cornish, Peter Dinklage and Clarke Peters whose characters did not match up to the respected actors capabilities. In other words their performances were forgettable as they were peripheral roles in the film and the story line was suspect at best. Sam Rockwell and Frances McDormand won an Oscar each for their performances, and Woody Harrelson could have and maybe should have beaten out his co-star Sam Rockwell for best supporting actor, and kudos to them all but I did not think this film was worthy of receiving six (6) Oscar nominations.
Most disappointing was the abrupt ending after watching the film for near to two (2) hours which I will not divulge so as not to have to provide a spoiler alert. Maybe the Cohen brothers have plans for a sequel but that would be nothing more than sheer box office greed leaning on their suprising six (6) Academy Award nominations and two (2) winns to which I for one will not be fooled. Fool me once, shame on you. Fool me twice, shame on me.
I give the film a decent 6 out of 10 rating but Academy Award recipient, I think not.
