should I watch this?

I don't get this. You want other people to make up your mind for you?

Heres a prediction of the responses you will get...some will say yes its worth watching, some will say its terrible.

Let's say more people say its worth watching and so you watch it, you may hate it and wonder why others recommended it. And vice versa.

You were given a brain for a reason....

Have you played the games? Then no.

It was decent for a video game movie.

I found it kind of bland myself

only if you have nothing else to watch.

Uh, do whatever you want. If the movie interests you in the slightest than watch it. Why complicate things? There's many ways you can watch it if you're skeptical but have interest. You can either pay full price, wait till it gets cheap years later. It'll be at thrift stores for like 2-3.99 eventually (I know because I bought a Blu-ray copy of many good movies from there years after said movies release), or wait for it to appear on a streaming service.

Nope.
It is a bad movie. A waste of 2 hours.
There are literally a million better ways to spend your time, even if you watch it for free.
