First, what makes a good movie? Is it having an A-list actor, a multi-million dollar budget, elaborate sets, exotic locations, and produced by one of the mega studios? If any of the above is among your criteria, then don't waste your time, because this movie is definitely not for you. For starters, a film such as "Collider" is for those who have an appreciation for the hard work poured into the filmmaking process - from pre-production (scriptwriting, funding, casting) and production (principal photography) to post-production (editing and distribution). Mind you, low budget means $1M-$3M, so anything less would be categorized as micro-budget; many, therefore, would fall under what would be considered subatomic (we have to call it something). So it would only be fair to factor in the budget when judging a film.
As for actors, Hollywood is notorious for bloated big names and nepotism. So, when a casting director discovers a gem of a find, such as the lead in this film, you can bet your bottom dollar that the talent will be bankable, as the producers behind this movie did, so much so that a whole movie was commissioned to be written with the specific actor, rather, actress, in mind (and other reputable teams have actually lined up to do the same). It should be no surprise if someday this fine young actress, who went far and beyond her comfort zone to meet the demands of this particular film, is recognized for her raw performance and natural talent.
As for the team, you don't know them yet, but they are actually, believe it or not, award-winning. Check them out and someday you will count yourself fortunate to have found them in their very beginnings.
Now, the storyline. As the others have already pointed out, there is, apparently, none. If you are the type who'd rather be spoonfed and follow a straight, direct, and linear path, then, I say it again, this movie is not for you. You're better off watching a rerun of "Seinfeld" for the nth time for a guaranteed dose of a good, healthy chuckle. Sometimes less is good; the more brainless the better. And many have made tons of money churning out pure and empty trash. (Not to say "Seinfeld" is trash. In fact, it's pure genius to make something out of nothing.) If, however, you are up to the challenge of figuring things out on your own, of retracing your steps to find out why things are, where things went wrong or how it all even began, of doing things over and over again until you get it right, then this movie may very well be for you. There is quite a bit of thinking involved to be able to follow this film and, if that sounds too exhausting, then just take the extra time to get a good night's sleep, because you may just find this movie so intriguing that it will keep you up all night thinking about the shoulda, coulda, woulda. Should you so choose to explore the film, you've been warned. You won't get your hour-and-a-half back, but, at the very least, your brain will surely reach optimal levels of mental activity which is not such a bad return on investment (now only $3.99 on Amazon Prime Video). Again, if the very concept of time travel confuses and frustrates you, do spare yourself the headache. You will just be lost in time with the going back and forth and, quite possibly and unfortunately for the rest of us, you might never again be found. If you did already endeavor to watch it and found yourself utterly lost, then, I'm sorry, but, unlike the lucky few, you simply just don't get it. It happens.
In the end, we are all entitled to our own opinion which is subjective and based on personal perspective. Someone else's trash is another man's treasure. "Collider" is either or both, a hit or a miss or somewhere in between depending on who you are. Glass half empty or glass half full? Perhaps, instead of taking the word of a self-proclaimed "one- or no-star" movie aficionado whose mission is to annihilate one unworthy movie after another, you would rather see for yourself what all the fuss (or no fuss) is about, to that I say, "Good for you!" As a fairly-respected movie critic emphasized, "'Collider' is a watchable film." I agree. After all, no less than Sony Pictures figured it was worth putting their stamp on and that's no easy feat to achieve.
Finally, I find the journey to be better the second, third, and even the fourth time around. I dare you to be the next Collider and see how you like traveling back and forth in time. Just make sure that CID doesn't capture and brainwash you. And, while you're at it, let me know what the heck it means -- Certifiably Insanely-Jealous Dudes? Remember, "One decision can change everything about you." Your decision to dive into the wormhole might just make you end up liking this "bad movie" after all!
In parting, I apologize if you find my review to be a pure waste of your precious time, but, give me a break, I read yours, too. Peace!
