There isn't anything new here and it has all been done a lot better before, but it isn't awful and considering the budget I'd call it OK.
They have borrowed a lot from other movies but primarily from Resident Evil (2002), although the limited budget means that it isn't on anything like the same scale.
If you do something that has very much been done before you need to have some twist or gimmick and here there is neither and the end leaves much to be desired as well.
If the ending had had a twist or at least tied it all together then this could have earned a couple of points more, but as it is you should only watch it if - like me - you watch everything with bio-weapons and even then there are very many movies that should be higher on your list like: Outbreak (1995), Contagion (2011) or 28 Days Later (2002) to name just a few that are in a similar genre.
