Total let down to the Alient franchise

Rating: 3/10 (30 September 2017)

I feel I've just wasted 2hrs of my Saturday evening watching this. Thank god I only paid 99p to rent it out and not £14.99 for the DVD and I'm glad as well I didn't pay to see in the cinema.
The crew of the Covenant are heading to a distant planet called Origai-6 to start a new human colony. While in hyper sleep the ship is damaged by a solar flare and the crew are woken up by Walter (Michael Fassbender). Having carried out repairs a crew member starts heading back but receives an unknown radio transmission of someone singing John Denver. Hey even in 2104 they're still listening to John Denver. They track where the signal is coming from and decide to take a look as it might be a better planet.
They arrive and start exploring the planet where they discover that wheat is growing within the vegetation and also there is no sound of animals. 2 crew members decide to stay behind to take samples while the rest track down the source of the signal.
This is where the 'fun' begins, While going to take a leak, of course you'd do that on a new planet without thinking will it destroy the Eco system. 1 member steps on what appears to be pods of some kind which releases a nano pathogen into the atmosphere. Which in turn enters the body of said person taking a leak
The other party discover the source and realise that this could be the Prometheus the ship missing some 10 years ago. While searching around another person then steps on some more pods and they release the nano pathogens, this time entering up the nose of the unsuspecting victim.
Victim #1 becomes sick and is taken back to the landing craft medical bay where he proceeds to explode from the back and release an alien. Second victim becomes sick and they start heading back for the ship. Meanwhile unable to make contact with the Covenant due a looming Ion storm the alien goes on the rampage killing those on board. Just as the other half of the party arrives the landing craft explodes killing alien and 1 remaining crew member.
By the time I'd got to this scene I had all but given up watching the film but thought I'd carry on and give it a chance.
The second alien emerges from sick crew member and goes on the rampage but it's scared off by a mysterious man who is wearing a cloak. This turns out to be Walters brother David from the Prometheus. In these 10 years since it went missing David has lost a cog or two and it turns out the planet did have an alien race on it but David deliberately released the pathogens which resulted in wiping out the alien race and creating another species. Plus it seems David has been experimenting as well.
After this I totally switched off and to be honest the plot was going no where I'd not warmed to any of the characters and I was just preying that they'd all be picked off one by one. As it is two, along with David survive and the ending was truly dire as well and could be seen before it got there.
With Alien you warmed to the crew of the Nostromo and hoped they'd survive. Aliens was all action and of course you had Newt who was almost as tough as Ellen Ripley. Alien3 you had Charles Dances character and the brash and straight to the point Andrews played by the late Brian Glover. All characters you could warm to.
This had nothing going for it. Crew member Daniels just whinged and questioned everything and then some how by default became Captain of the Covenant. All other crew members were well boring! No strength or depth to them.
It's a real shame as I had high hopes for this. Sadly it is a total let down from start to finish and it won't please the die hard Alien fanatics that's for sure,
